RING-CH finger, H2 subclass (C4HC3-type), found in non-structural maintenance of chromosomes (SMC) element 1 homolog (NSE1) and similar proteins; NSE1, also known as non-SMC element 1 homolog (NSMCE1), is an E3 ubiquitin ligase that contains a C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger. Together with its partner proteins NSE3 and NSE4, it forms a tight subcomplex of the SMC5-6 complex, which includes another two subcomplexes, SMC6-SMC5-NSE2 and NSE5-NSE6. The vRING finger is essential for normal NSE1-NSE3-NSE4 trimer formation in vitro and for damage-induced recruitment of NSE4 and SMC5 to subnuclear foci in vivo. Thus it functions as a protein-protein interaction domain required for SMC5-6 holocomplex integrity and recruitment to, or retention at, DNA lesions. The C-terminal half of NSE1, including the vRING finger, is required for DNA damage resistance and mitotic fidelity of SMC5-6 complex in the fission yeast Schizosaccharomyces pombe. The RING-CH finger may play an important role in Rad52-dependent post-replication repair of UV-damaged DNA in Saccharomyces cerevisiae.

protein kinase C conserved region 1 (C1 domain) found in the Raf (Rapidly Accelerated Fibrosarcoma) kinase family; Raf kinases are serine/threonine kinases (STKs) that catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. They act as mitogen-activated protein kinase kinase kinases (MAP3Ks, MKKKs, MAPKKKs), which phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. They function in the linear Ras-Raf-MEK-ERK pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. Aberrant expression or activation of components in this pathway are associated with tumor initiation, progression, and metastasis. Raf proteins contain a Ras binding domain, a zinc finger cysteine-rich domain (C1), and a catalytic kinase domain. Vertebrates have three Raf isoforms (A-, B-, and C-Raf) with different expression profiles, modes of regulation, and abilities to function in the ERK cascade, depending on cellular context and stimuli. They have essential and non-overlapping roles during embryo- and organogenesis. Knockout of each isoform results in a lethal phenotype or abnormality in most mouse strains. This model describes the C1 domain. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

first protein kinase C conserved region 1 (C1 domain) found in type III diacylglycerol kinase, DAG kinase epsilon, and similar proteins; Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. DAG kinase epsilon, also called diglyceride kinase epsilon (DGK-epsilon), is the only isoform classified as type III; it possesses a hydrophobic domain in addition to C1 and catalytic domains that are present in all DGKs, and shows selectivity for acyl chains. It is highly selective for arachidonate-containing species of DAG. It may terminate signals transmitted through arachidonoyl-DAG or may contribute to the synthesis of phospholipids with defined fatty acid composition. DAG kinase epsilon contains two copies of the C1 domain. This model corresponds to the first one. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

RING-CH finger, H2 subclass (C4HC3-type), found in E3 ubiquitin-protein ligase listerin and similar proteins; Listerin, also known as RING finger protein 160 or zinc finger protein 294, is the mammalian homolog of yeast Ltn1. It is widely expressed in all tissues, but motor and sensory neurons and neuronal processes in the brainstem and spinal cord are primarily affected in the mutant. Listerin is required for embryonic development and plays an important role in neurodegeneration. It also functions as a critical E3 ligase involving quality control of nonstop proteins. It mediates ubiquitylation of aberrant proteins that become stalled on ribosomes during translation. Ltn1 works with several cofactors to form a large ribosomal subunit-associated quality control complex (RQC), which mediates the ubiquitylation and extraction of ribosome-stalled nascent polypeptide chains for proteasomal degradation. It appears to first associate with nascent chain-stalled 60S subunits together with two proteins of unknown function, Tae2 and Rqc1. Listerin contains a long stretch of HEAT (Huntingtin, Elongation factor 3, PR65/A subunit of protein phosphatase 2A, and TOR) or ARM (Armadillo) repeats in the N terminus and middle region, and a catalytic RING-CH finger, also known as vRING or RINGv, with an unusual arrangement of zinc-coordinating residues in the C-terminus . Its cysteines and histidines are arranged in the sequence as C4HC3-type, rather than the C3H2C3-type in canonical RING-H2 finger.

protein kinase C conserved region 1 (C1 domain) found in the Myotonic dystrophy kinase-related Cdc42-binding kinase (MRCK) family; MRCK is thought to be a coincidence detector of signaling by the small GTPase Cdc42 and phosphoinositides. MRCK/Cdc42 signaling mediates myosin-dependent cell motility. MRCK has been shown to promote cytoskeletal reorganization, which affects many biological processes. Three isoforms of MRCK are known, named alpha, beta and gamma. MRCKgamma is expressed in heart and skeletal muscles, unlike MRCKalpha and MRCKbeta, which are expressed ubiquitously. MRCK consists of a serine/threonine kinase domain, a cysteine rich (C1) region, a PH domain and a p21 binding motif. This model corresponds to C1 domain. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

protein kinase C conserved region 1 (C1 domain) found in B-Raf (Rapidly Accelerated Fibrosarcoma) kinase and similar proteins; Serine/threonine-protein kinase B-Raf, also called proto-oncogene B-Raf, p94, or v-Raf murine sarcoma viral oncogene homolog B1, activates ERK with the strongest magnitude, compared with other Raf kinases. Mice embryos deficient in B-Raf die around midgestation due to vascular hemorrhage caused by apoptotic endothelial cells. Mutations in B-Raf have been implicated in initiating tumorigenesis and tumor progression, and are found in malignant cutaneous melanoma, papillary thyroid cancer, as well as in ovarian and colorectal carcinomas. Most oncogenic B-Raf mutations are located at the activation loop of the kinase and surrounding regions; the V600E mutation accounts for around 90% of oncogenic mutations. The V600E mutant constitutively activates MEK, resulting in sustained activation of ERK. B-Raf is a mitogen-activated protein kinase kinase kinase (MAP3K, MKKK, MAPKKK), which phosphorylates and activates MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals.
