12-122 7.57e-85

C2 domain present in Toll-interacting protein (Tollip); Tollip is a part of the Interleukin-1 receptor (IL-1R) signaling pathway. Tollip is proposed to link serine/threonine kinase IRAK to IL-1Rs as well as inhibiting phosphorylation of IRAK. There is a single C2 domain present in Tollip. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

180-220 3.84e-24

CUE domain found in the C-terminal of toll-interacting protein (Tollip) and similar proteins; Tollip is a new component of the IL-1RI pathway which contains an N-terminal C2 domain and a C-terminal CUE domain. Tollip binds to the cytoplasmic TIR domain of IL-1Rs after IL-1 stimulation. It is sufficient for recruitment of IRAK to IL-1Rs and negatively regulates IL-1-induced signaling by inhibiting IRAK phosphorylation. In addition, Tollip directly interacts with toll-like receptors TLR2 and TLR4, and plays an inhibitory role in TLR-mediated cell activation through suppressing phosphorylation and kinase activity of IRAK. Moreover, Tollip can associate with GAT domains of Tom1 and its related proteins Tom1L1 and Tom1L2, and facilitate the recruitment of clathrin onto endosomes.

181-218 1.53e-11

CUE domain found in ubiquitin-binding CUE proteins; This family includes many coupling of ubiquitin conjugation to endoplasmic reticulum degradation (CUE) domain containing proteins that are characterized by an FP and a di-leucine-like sequence and bind to monoubiquitin with varying affinities. Some higher eukaryotic CUE domain proteins do not bind monoubiquitin efficiently, since they carry LP, rather than FP among CUE domains. CUE domains form three-helix bundle structures and are distantly related to the ubiquitin-associated (UBA) domains which are widely occurring ubiquitin-binding motifs found in a broad range of cellular proteins in species ranging from yeast to human. The majority of family members contain one CUE domain, but some family members from fungi harbor two CUE domains.

C2 domain found in fungal Ingression 1 (Inn1) proteins; Saccharomyces cerevisiae Inn1 associates with the contractile actomyosin ring at the end of mitosis and is needed for cytokinesis. The C2 domain of Inn1, located at the N-terminus, is required for ingression of the plasma membrane. The C-terminus is relatively unstructured and contains eight PXXP motifs that are thought to mediate interaction of Inn1 with other proteins with SH3 domains in the cytokinesis proteins Hof1 (an F-BAR protein) and Cyk3 (whose overexpression can restore primary septum formation in Inn1Delta cells) as well as recruiting Inn1 to the bud-neck by binding to Cyk3. Inn1 and Cyk3 appear to cooperate in activating chitin synthase Chs2 for primary septum formation, which allows coordination of actomyosin ring contraction with ingression of the cleavage furrow. It is thought that the C2 domain of Inn1 helps to preserve the link between the actomyosin ring and the plasma membrane, contributing both to membrane ingression, as well as to stability of the contracting ring. Additionally, Inn1 might induce curvature of the plasma membrane adjacent to the contracting ring, thereby promoting ingression of the membrane. It has been shown that the C2 domain of human synaptotagmin induces curvature in target membranes and thereby contributes to fusion of these membranes with synaptic vesicles. The C2 domain was first identified in PKC. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

181-220 8.65e-09

CUE domain found in vacuolar protein sorting-associated protein 9 (VPS9) and similar proteins; VPS9, also called vacuolar protein-targeting protein 9, is a cytosolic yeast protein required for localization of vacuolar proteins, such as the soluble vacuolar hydrolases CPY and PrA. It may bind and act as an effector of a rab GTPase and plays a role in vacuolar protein sorting (VPS) pathway. VPS9 contains a region called GBH domain that is related to mammalian Ras-binding proteins, Rin1 and JC265, and may negatively regulate Ras-mediated signaling in yeast Saccharomyces cerevisiae. This model corresponds to the N-terminal CUE domain that interacts specifically with monoubiquitin and regulates intramolecular monoubiquitylation.

C2 domain first and third repeat in Synaptotagmin-like proteins; Synaptotagmin is a membrane-trafficking protein characterized by a N-terminal transmembrane region, a linker, and 2 C-terminal C2 domains. Previously all synaptotagmins were thought to be calcium sensors in the regulation of neurotransmitter release and hormone secretion, but it has been shown that not all of them bind calcium. Of the 17 identified synaptotagmins only 8 bind calcium (1-3, 5-7, 9, 10). The function of the two C2 domains that bind calcium are: regulating the fusion step of synaptic vesicle exocytosis (C2A) and binding to phosphatidyl-inositol-3,4,5-triphosphate (PIP3) in the absence of calcium ions and to phosphatidylinositol bisphosphate (PIP2) in their presence (C2B). C2B also regulates also the recycling step of synaptic vesicles. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins.

C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. This cd contains either the first or third repeat in Synaptotagmin-like proteins with a type-I topology.

C2 domain present in Soybean genes Regulated by Cold 2 (SRC2)-like proteins; SRC2 production is a response to pathogen infiltration. The initial response of increased Ca2+ concentrations are coupled to downstream signal transduction pathways via calcium binding proteins. SRC2 contains a single C2 domain which localizes to the plasma membrane and is involved in Ca2+ dependent protein binding. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins.

UBA domain-like superfamily; The ubiquitin-associated (UBA) domain-like superfamily contains alpha-helical structural homology ubiquitin-binding domains, including UBA domains and coupling of ubiquitin conjugation to endoplasmic reticulum degradation (CUE) domains which share a common three-helical bundle architecture. UBA domains are commonly occurring sequence motifs found in proteins involved in ubiquitin-mediated proteolysis. They contribute to ubiquitin (Ub) binding or ubiquitin-like (UbL) domain binding. However, some kinds of UBA domains can only bind the UbL domain, but not the Ub domain. UBA domains are normally comprised of compact three-helix bundles which contain a conserved GF/Y-loop. They can bind polyubiquitin with high affinity. They also bind monoubiquitin and other proteins. Most UBA domain-containing proteins have one UBA domain, but some harbor two or three UBA domains. CUE domain containing proteins are characterized by an FP and a di-leucine-like sequence and bind to monoubiquitin with varying affinities. Some higher eukaryotic CUE domain proteins do not bind monoubiquitin efficiently, since they carry LP, rather than FP among CUE domains. This superfamily also includes many UBA-like domains found in AMP-activated protein kinase (AMPK) related kinases, the NXF family of mRNA nuclear export factors, elongation factor Ts (EF-Ts), nascent polypeptide-associated complex subunit alpha (NACA) and similar proteins. Although many UBA-like domains may have a conserved TG but not GF/Y-loop, they still show a high level of structural and sequence similarity with three-helical ubiquitin binding domains.

24-122 2.78e-04

C2 domain present in the Human neural precursor cell-expressed, developmentally down-regulated 4 (NEDD4) and NEDD4-like (NEDD4L/NEDD42); Nedd4 and Nedd4-2 are two of the nine members of the Human Nedd4 family. All vertebrates appear to have both Nedd4 and Nedd4-2 genes. They are thought to participate in the regulation of epithelial Na+ channel (ENaC) activity. They also have identical specificity for ubiquitin conjugating enzymes (E2). Nedd4 and Nedd4-2 are composed of a C2 domain, 2-4 WW domains, and a ubiquitin ligase Hect domain. Their WW domains can bind PPxY (PY) or LPSY motifs, and in vitro studies suggest that WW3 and WW4 of both proteins bind PY motifs in the key substrates, with WW3 generally exhibiting higher affinity. Most Nedd4 family members, especially Nedd4-2, also have multiple splice variants, which might play different roles in regulating their substrates. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

25-106 3.13e-04

C2 domain present in RAS p21 protein activator 1 (RasA1); RasA1 is a GAP1 (GTPase activating protein 1), a Ras-specific GAP member, which suppresses Ras function by enhancing the GTPase activity of Ras proteins resulting in the inactive GDP-bound form of Ras. In this way it can control cellular proliferation and differentiation. RasA1 contains a C2 domain, a Ras-GAP domain, a pleckstrin homology (PH)-like domain, a SH3 domain, and 2 SH2 domains. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions. Members here have a type-I topology.

C2 domain present in the putative elicitor-responsive gene; In plants elicitor-responsive proteins are triggered in response to specific elicitor molecules such as glycolproteins, peptides, carbohydrates and lipids. A host of defensive responses are also triggered resulting in localized cell death. Antimicrobial secondary metabolites, such as phytoalexins, or defense-related proteins, including pathogenesis-related (PR) proteins are also produced. There is a single C2 domain present here. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins.

181-220 8.23e-04

CUE domain found in NEDD4-binding protein 2 (N4BP2) and similar proteins; N4BP2 has been identified as an oncogene bcl-3 coding protein BCL-3-binding protein (B3BP) that participates in connecting transcriptional activation and genetic recombination of the Ig gene. In addition to BCL-3, it also interacts with p300/CBP histone acetyltransferases. N4BP2 shows intrinsic ATP binding and hydrolyzing activity. It contains an N-terminal ATP-binding region that is responsible for the interaction with BCL-3 and p300/CBP. N4BP2 also functions as a 5'-polynucleotide kinase that can transfer a phosphate group to the 5' end of DNA and RNA substrates. Moreover, N4BP2 contains a C-terminal MutS-related domain that possesses nicking endonuclease activity and may play a role in DNA mismatch repair (MMR). This model corresponds to CUE domain in the N-terminus of N4BP2.

24-79 9.83e-04

C2 domain present in Arf GTPase Activating Proteins (GAP); ArfGAP is a GTPase activating protein which regulates the ADP ribosylation factor Arf, a member of the Ras superfamily of GTP-binding proteins. The GTP-bound form of Arf is involved in Golgi morphology and is involved in recruiting coat proteins. ArfGAP is responsible for the GDP-bound form of Arf which is necessary for uncoating the membrane and allowing the Golgi to fuse with an acceptor compartment. These proteins contain an N-terminal ArfGAP domain containing the characteristic zinc finger motif (Cys-x2-Cys-x(16,17)-x2-Cys) and C-terminal C2 domain. C2 domains were first identified in Protein Kinase C (PKC). C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins.
