 224-445 2.68e-163

MIR domain, beta-trefoil fold, found in inositol 1,4,5-trisphosphate receptor type 1 (ITPR1) and similar proteins; ITPR1, also called IP3 receptor isoform 1 (IP3R 1), or InsP3R1, or type 1 inositol 1,4,5-trisphosphate receptor, or type 1 InsP3 receptor, is an intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate. It is involved in the regulation of epithelial secretion of electrolytes and fluid through the interaction with AHCYL1. It plays a role in endoplasmic reticulum (ER) stress-induced apoptosis. ITPR1 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

Inositol 1,4,5-trisphosphate/ryanodine receptor; This domain corresponds to the ligand binding region on inositol 1,4,5-trisphosphate receptor, and the N terminal region of the ryanodine receptor. Both receptors are involved in Ca2+ release. They can couple to the activation of neurotransmitter-gated receptors and voltage-gated Ca2+ channels on the plasma membrane, thus allowing the endoplasmic reticulum discriminate between different types of neuronal activity.

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.

 224-445 2.68e-163

MIR domain, beta-trefoil fold, found in inositol 1,4,5-trisphosphate receptor type 1 (ITPR1) and similar proteins; ITPR1, also called IP3 receptor isoform 1 (IP3R 1), or InsP3R1, or type 1 inositol 1,4,5-trisphosphate receptor, or type 1 InsP3 receptor, is an intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate. It is involved in the regulation of epithelial secretion of electrolytes and fluid through the interaction with AHCYL1. It plays a role in endoplasmic reticulum (ER) stress-induced apoptosis. ITPR1 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

 224-440 1.26e-143

MIR domain, beta-trefoil fold, found in the family of inositol 1,4,5-trisphosphate receptor (ITPR); Inositol 1,4,5 trisphosphate receptors (ITPRs) are a family of endoplasmic reticulum Ca2+ channels essential for the control of intracellular Ca2+ levels in virtually every mammalian cell type. Calcium-mediated signaling through ITPRs is essential for the regulation of numerous physiological processes, including fertilization, muscle contraction, apoptosis, secretion, and synaptic plasticity. The ITPR family includes three isoforms (ITPR1, ITPR2 and ITPR3), which can control different cellular processes due to their unique biophysical properties, subcellular localization, and tissue distribution. ITPRs contain an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

MIR domain, beta-trefoil fold, found in inositol 1,4,5-trisphosphate receptor type 2 (ITPR2) and similar proteins; ITPR2, also called IP3 receptor isoform 2 (IP3R 2), or InsP3R2, or type 2 inositol 1,4,5-trisphosphate receptor, or type 2 InsP3 receptor, is a key regulator for the activity of calcium ion transmembrane transportation, which plays a critical role in cell cycle and proliferation. It is a receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium. This release is regulated by cAMP both dependently and independently of cAMP-dependent protein kinase (PKA). ITPR2 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

Inositol 1,4,5-trisphosphate/ryanodine receptor; This domain corresponds to the ligand binding region on inositol 1,4,5-trisphosphate receptor, and the N terminal region of the ryanodine receptor. Both receptors are involved in Ca2+ release. They can couple to the activation of neurotransmitter-gated receptors and voltage-gated Ca2+ channels on the plasma membrane, thus allowing the endoplasmic reticulum discriminate between different types of neuronal activity.

 231-440 3.71e-32

MIR domain, beta-trefoil fold, found in Caenorhabditis elegans inositol 1,4,5-trisphosphate receptor Itr-1 and similar proteins; Itr-1, also called IP3 receptor, or IP3R, or InsP3R, or LET-23 fertility effector 1, is a receptor for inositol 1,4,5-trisphosphate, a second messenger that regulates intracellular calcium homeostasis. It binds in vitro to both inositol 1,4,5-trisphosphate (1,4,5-InsP3) and inositol 2,4,5-trisphosphate (2,4,5-InsP3) with high affinity. It can also bind inositol 1,3,4,5-tetrakisphosphate (1,3,4,5-InsP4) and inositol 4,5-bisphosphate (4,5-InsP2), but with lower affinity. Itr-1 acts as a timekeeper/rhythm generator via calcium signaling, affecting the defecation cycle and pharyngeal pumping. It affects normal hermaphrodite and male fertility as a participant in intracellular signaling by acting downstream of let-23/lin-3 which regulates ovulation, spermathecal valve dilation and male mating behavior. It plays an important role in early embryonic development. It controls epidermal cell migration and may also regulate filopodial protrusive activity during epithelial morphogenesis. Itr-1 functions as a component of inositol trisphosphate (IP3)-mediated downstream signaling pathways that controls amphid sensory neuronal (ASH)-mediated response to nose touch and benzaldehyde, but no other ASH-mediated responses. Itr-1 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.

MIR domain, beta-trefoil fold, found in ryanodine receptor 3 (RyR3) and similar proteins; RyR3, also called RYR-3, or brain ryanodine receptor-calcium release channel, or brain-type ryanodine receptor, or type 3 ryanodine receptor, is a calcium channel that plays a role in cellular calcium signaling. It mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm in muscle and thereby plays a role in triggering muscle contraction. It also mediates Ca(2+)-induced Ca(2+) release from the endoplasmic reticulum in non-muscle cells. RYR-3 forms homotetramer and also forms heterotetramer with RYR-2. RYR-3 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

 236-419 1.80e-05

MIR domain, beta-trefoil fold, found in the family of ryanodine receptor (RyR); RyRs (also called RYRs) are intracellular Ca(2+) release channels located on the sarco/endoplasmic reticulum (SR/ER). They release calcium Ca(2+) intracellular stores to activate critical functions including muscle contraction and neurotransmitter release. The family includes three closely homologous proteins, RyR1, RyR2 and RyR3. RyR1 is present in skeletal muscle; RyR2 is in heart muscle; and RyR3 is expressed at low levels in many tissues including brain, smooth muscle, and slow-twitch skeletal muscle. RYR2 is the major cellular mediator of calcium-induced calcium release (CICR) in animal cells. RyR1 and RyR2 release Ca2+ from the ER in response to excitation of muscle membranes to promote muscle contraction. RYR3 is involved in force production and calcium handling in extraocular muscle. RYRs contain an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

MIR domain, beta-trefoil fold, found in the family of dolichyl-phosphate-mannose-protein mannosyltransferase (PMT); The PMT (EC 2.4.1.109) family includes mammalian protein O-mannosyl-transferases (POMT1 and POMT2) and yeast PMT1-7. PMTs are responsible for O-linked glycosylation of proteins. They catalyze the transfer of mannose to seryl and threonyl residues of secretory proteins. Protein O-glycosylation is essential for cell wall rigidity and cell integrity. Members in this family contain a MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

MIR domain, beta-trefoil fold, found in ryanodine receptor 2 (RyR2) and similar proteins; RyR2, also called RYR-2, or cardiac muscle ryanodine receptor-calcium release channel, or cardiac muscle ryanodine receptor, or type 2 ryanodine receptor, is a calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering cardiac muscle contraction. Aberrant channel activation can lead to cardiac arrhythmia. In cardiac myocytes, calcium release is triggered by increased Ca(2+) levels due to activation of the L-type calcium channel CACNA1C. The calcium channel activity of RYR-2 is modulated by formation of heterotetramers with RYR-3. RYR-2 is required for cellular calcium ion homeostasis. it plays an essential role in embryonic heart development. RYR-2 forms homotetramer and also forms heterotetramers with RYR-1 and RYR-3. RYR-2 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

MIR domain, beta-trefoil fold, found in ryanodine receptor 1 (RyR1) and similar proteins; RyR1, also called RYR-1, or skeletal muscle calcium release channel, or skeletal muscle ryanodine receptor, or skeletal muscle-type ryanodine receptor, or type 1 ryanodine receptor, is a calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering muscle contraction following depolarization of T-tubules. It can also mediate the release of Ca(2+) from intracellular stores in neurons, and may thereby promote prolonged Ca(2+) signaling in the brain. It is required for normal embryonic development of muscle fibers and skeletal muscle, as well as for normal heart morphogenesis, skin development and ossification during embryogenesis. RYR-1 forms homotetramer and can also form heterotetramers with RYR-2. RYR-1 contains an N-terminal MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

 117-284 6.71e-03

MIR domain, beta-trefoil fold, found in family of stromal cell-derived factor 2 (SDF-2); The SDF-2 family includes mammalian SDF-2 and SDF2-like protein 1 (SDF2L1) as well as similar proteins from plant, such as Arabidopsis thaliana stromal cell-derived factor 2-like protein (AtSDF2). SDF-2 is a secretory protein involved in multiple endoplasmic reticulum (ER) functions, including the misfolded protein catabolic process, protein glycosylation, and ER protein quality control. SDF2L1, also called PWP1-interacting protein 8, is an endoplasmic reticulum (ER)-localized protein that plays a role in ER-associated degradation (ERAD) of misfolded proinsulin in pancreatic beta-cells. It is a component of the endoplasmic reticulum (ER) chaperone complex and interacts with alpha- and beta-defensins. SDF2L1 may also act as a tumor suppressor that play an important role in a variety of cancers, such as breast cancer and ovarian cancer. AtSDF2, also called SDF2-like protein, acts as crucial component of the unfolded protein response (UPR) in Arabidopsis thaliana. It is involved in the endoplasmic reticulum (ER) protein quality control and unfolded protein response. It may be involved in the quality control of glycoproteins. AtSDF2 forms a complex in the ER with ERDJ3B and MED37A/BIP1 which is required for the proper accumulation and function of the surface-exposed leucine-rich repeat receptor kinases EFR involved in pathogen-associated molecular pattern (PAMP) triggered immunity. Members in this family contain a MIR (protein mannosyltransferase, IP3R and RyR) domain with beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.
