START_STARD6-like cd08904
Lipid-binding START domain of mammalian STARD6 and related proteins; This subgroup includes ...
 1-215 2.18e-147

Lipid-binding START domain of mammalian STARD6 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD6 and related domains. It belongs to the START domain family, and in turn to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD6 is expressed in male germ cells of normal rats, and in the steroidogenic Leydig cells of perinatal hypothyroid testes. It may play a pivotal role in the steroidogenesis as well as in the spermatogenesis of normal rats. STARD6 has also been detected in the rat nervous system, and may participate in neurosteroid synthesis.

 1-215 1.55e-118

Lipid-binding START domain of mammalian STARD4, -5, -6, and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD4, -5, and -6. The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD4 plays an important role in steroidogenesis, trafficking cholesterol into mitochondria. It specifically binds cholesterol, and demonstrates limited binding to another sterol, 7a-hydroxycholesterol. STARD4 and STARD5 are ubiquitously expressed, with highest levels in liver and kidney. STRAD5 functions in the kidney within the proximal tubule cells where it is associated with the Endoplasmic Reticulum (ER), and may participate in ER-associated cholesterol transport. It binds cholesterol and 25-hydroxycholesterol. Expression of the gene encoding STARD5 is increased by ER stress, and its mRNA and protein levels are elevated in a type I diabetic mouse model of human diabetic nephropathy. STARD6 is expressed in male germ cells of normal rats, and in the steroidogenic Leydig cells of perinatal hypothyroid testes. It may play a pivotal role in the steroidogenesis as well as in the spermatogenesis of normal rats. STARD6 has also been detected in the rat nervous system, and may participate in neurosteroid synthesis.

 12-207 2.70e-36

Lipid-binding START domain of mammalian STARD1-STARD15 and related proteins; This family includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD1-STARD15, and related domains, such as the START domain of the Arabidopsis homeobox protein GLABRA 2. The mammalian STARDs are grouped into 8 subfamilies. This family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. For some members of this family, specific lipids that bind in this pocket are known; these include cholesterol (STARD1/STARD3/ STARD4/STARD5), 25-hydroxycholesterol (STARD5), phosphatidylcholine (STARD2/ STARD7/STARD10), phosphatidylethanolamine (STARD10) and ceramides (STARD11). The START domain is found either alone or in association with other domains. Mammalian STARDs participate in the control of various cellular processes including lipid trafficking between intracellular compartments, lipid metabolism, and modulation of signaling events. Mutation or altered expression of STARDs is linked to diseases such as cancer, genetic disorders, and autoimmune disease. The Arabidopsis homeobox protein GLABRA 2 suppresses root hair formation in hairless epidermal root cells.

It belongs to the START domain family, and in turn to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD4 plays an important role in steroidogenesis, trafficking cholesterol into mitochondria. It specifically binds cholesterol, and demonstrates limited binding to another sterol, 7alpha-hydroxycholesterol. STARD4 is ubiquitously expressed, with highest levels in liver and kidney.

Cholesterol-binding START domain of mammalian STARD1, -3 and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD1 (also known as StAR) and STARD3 (also known as metastatic lymph node 64/MLN64). The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. This STARD1-like subfamily has a high affinity for cholesterol. STARD1/StAR can reduce macrophage lipid content and inflammatory status. It plays an essential role in steroidogenic tissues: transferring the steroid precursor, cholesterol, from the outer to the inner mitochondrial membrane, across the aqueous space. Mutations in the gene encoding STARD1/StAR can cause lipid congenital adrenal hyperplasia (CAH), an autosomal recessive disorder characterized by a steroid synthesis deficiency and an accumulation of cholesterol in the adrenal glands and the gonads. STARD3 may function in trafficking endosomal cholesterol to a cytosolic acceptor or membrane. In addition to having a cytoplasmic START cholesterol-binding domain, STARD3 also contains an N-terminal MENTAL cholesterol-binding and protein-protein interaction domain. The MENTAL domain contains transmembrane helices and anchors MLN64 to endosome membranes. The gene encoding STARD3 is overexpressed in about 25% of breast cancers.

C-terminal START domain of mammalian STARD9, and related domains; lipid binding; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD9 (also known as KIAA1300), and related domains. The START domain family belongs to the SRPBCC (START/RHO_alpha_C /PITP /Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. Some members of this subfamily have N-terminal kinesin motor domains. STARD9 interacts with supervillin, a protein important for efficient cytokinesis, perhaps playing a role in coordinating microtubule motors with actin and myosin II functions at membranes. The human gene encoding STARD9 lies within a target region for LGMD2A, an autosomal recessive form of limb-girdle muscular dystrophy.

Lipid-binding START domain of mammalian STARDT14, -15, and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian brown fat-inducible STARD14 (also known as Acyl-Coenzyme A Thioesterase 11 or ACOT11, BFIT, THEA, THEM1, KIAA0707, and MGC25974), STARD15/ACOT12 (also known as cytoplasmic acetyl-CoA hydrolase/CACH, THEAL, and MGC105114), and related domains. The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD14/ACOT11 and STARD15/ACOT12 are type II acetyl-CoA thioesterases; they catalyze the hydrolysis of acyl-CoAs to free fatty acid and CoASH. Human STARD14 displays acetyl-CoA thioesterase activity towards medium(C12)- and long(C16)-chain fatty acyl-CoA substrates. Rat CACH hydrolyzes acetyl-CoA to acetate and CoA. In addition to having a START domain, STARD14 and STARD15 each have two tandem copies of the hotdog domain. There are two splice variants of human STARD14, named BFIT1 and BFIT2, which differ in their C-termini. Human BFIT2 is equivalent to mouse mBFIT/Acot11, whose transcription is increased two fold in obesity-resistant mice compared with obesity-prone mice. Human STARD15 may have roles in cholesterol metabolism and in beta-oxidation.

 42-207 2.51e-07

Lipid-binding START domain of mammalian STARD10 and related proteins; This subfamily includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian STARD10 (also known as CGI-52, PTCP-like, and SDCCAG28). The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD10 binds phophatidylcholine and phosphatidylethanolamine. This protein is widely expressed and is synthesized constitutively in many organs. It may function in the liver in the export of phospholipids into bile. It is concentrated in the sperm flagellum, and may play a role in energy metabolism. In the mammary gland it may participate in the enrichment of lipids in milk, and be a potential marker of differentiation. Its expression is induced in this gland during gestation and lactation. It is overexpressed in mammary tumors from Neu/ErbB2 transgenic mice, in several breast carcinoma cell lines, and in 35% of primary human breast cancers, and may cooperate with c-erbB receptor signaling in breast oncogenesis. It is a potential marker of disease outcome in breast cancer; loss of STARD10 expression in breast cancer strongly predicts an aggressive disease course. The lipid transfer activity of STRAD10 is downregulated by phosphorylation of its Ser284 by CK2 (casein kinase 2).

 59-183 1.21e-06

Lipid-binding START domain of mammalian STARDT14 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of mammalian brown fat-inducible STARD14 (also known as Acyl-Coenzyme A Thioesterase 11 or ACOT11, BFIT, THEA, THEM1, KIAA0707, and MGC25974) and related proteins. It belongs to the START domain family, and in turn to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD14/ACOT11 is a type II acetyl-CoA thioesterase; it catalyzes the hydrolysis of acyl-CoAs to free fatty acid and CoASH. Human STARD14 displays acetyl-CoA thioesterase activity towards medium(C12)- and long(C16)-chain fatty acyl-CoA substrates. In addition to having a START domain, most proteins in this subgroup have two tandem copies of the hotdog domain. There are two splice variants of human STARD14, named BFIT1 and BFIT2, which differ in their C-termini. Human BFIT2 is equivalent to mouse mBFIT/Acot11, whose transcription is increased two fold in obesity-resistant mice compared with obesity-prone mice.

 67-172 2.06e-04

Lipid-binding START domain of mammalian STARD15 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD15/ACOT12 (also known as cytoplasmic acetyl-CoA hydrolase/CACH, THEAL, and MGC105114) and related domains. It belongs to the START domain family, and in turn to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD15/ACOT12 is a type II acetyl-CoA thioesterase; it catalyzes the hydrolysis of acyl-CoAs to free fatty acid and CoASH. Rat CACH hydrolyzes acetyl-CoA to acetate and CoA. In addition to having a START domain, most proteins in this subgroup have two tandem copies of the hotdog domain. Human STARD15/ACOT12 may have roles in cholesterol metabolism and in beta-oxidation.

 18-156 3.43e-03

Lipid-binding START domain of mammalian STARD7 and related proteins; This subgroup includes the steroidogenic acute regulatory protein (StAR)-related lipid transfer (START) domains of STARD7 (also known as gestational trophoblastic tumor 1/GTT1). It belongs to the START domain family, and in turn to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. The gene encoding STARD7 is overexpressed in choriocarcinoma. STARD7 appears to be involved in the intracellular trafficking of phosphatidycholine (PtdCho) to mitochondria. STARD7 was shown to be surface active and to interact differentially with phospholipid monolayers, it showed a preference for phosphatidylserine, cholesterol, and phosphatidylglycerol.
