Rab11-family interacting proteins (FIPs) are involved in mediating the role of Rab11. FIPs can be divided into three classes: class I FIPs (Rip11a, Rip11b, RCP, and FIP2) which contain a C2 domain after N-terminus of the protein, class II FIPs (FIP3 and FIP4) which contain two EF-hands and a proline rich region, and class III FIPs (FIP1) which exhibits no homology to known protein domains. All FIP proteins contain a highly conserved, 20-amino acid motif at the C-terminus of the protein, known as Rab11/25 binding domain (RBD). Class I FIPs are thought to bind to endocytic membranes via their C2 domain, which interacts directly with phospholipids. Class II FIPs do not have any membrane binding domains leaving much to speculate about the mechanism involving FIP3 and FIP4 interactions with endocytic membranes. The member

>cd08681 C2_fungal_Inn1p-like 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, contr

Ferlins and other proteins, such as Synaptotagmins, are implicated in facilitating the fusion process when cell membranes fuse together. There are six known human Ferlins: Dysferlin (Fer1L1), Otoferlin (Fer1L2), Myoferlin (Fer1L3), Fer1L4, Fer1L5, and Fer1L6. Defects in these genes can lead to a wide range of diseases including muscular dystrophy (dysferlin), deafness (otoferlin), and infertility (fer-1, fertilization factor-1). Structurally they have 6 tandem C2 domains, designated as (C2A-C2F) and a single C-terminal transmembrane domain, though there is a new study that disputes this and claims that there are actually 7 tandem C2 domains with another C2 domain inserted between C2D and C2E.

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.

Ferlins and other proteins, such as Synaptotagmins, are implicated in facilitating the fusion process when cell membranes fuse together. There are six known human Ferlins: Dysferlin (Fer1L1), Otoferlin (Fer1L2), Myoferlin (Fer1L3), Fer1L4, Fer1L5, and Fer1L6. Defects in these genes can lead to a wide range of diseases including muscular dystrophy (dysferlin), deafness (otoferlin), and infertility (fer-1, fertilization factor-1). Structurally they have 6 tandem C2 domains, designated as (C2A-C2F) and a single C-terminal transmembrane domain, though there is a new study that disputes this and claims that there are actually 7 tandem C2 domains with another C2 domain inserted between C2D and C2E. In a subset of them (Dysferlin, Myoferlin, and Fer1) there is an additional conserved domain called DysF. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangemen

Synaptotagmin is a membrane-trafficking protein characterized by a N-terminal transmembrane region, a linker, and 2 C-terminal C2 domains.

>cd08390 C2A_Synaptotagmin-15-17 C2A domain first repeat present in Synaptotagmins 15 and 17. Synaptotagmin is a membrane-trafficking protein characterized by a N-terminal transmembrane region, a linker, and 2 C-terminal C2 domains. It is thought to be involved in the trafficking and exocytosis of secretory vesicles in non-neuronal tissues and is Ca2+ independent. Human synaptotagmin 15 has 2 alternatively spliced forms that encode proteins with different C-termini. The larger, SYT15a, contains a N-terminal TM region, a putative fatty-acylation site, and 2 tandem C terminal C2 domains. The smaller, SYT15b, lacks the C-terminal portion of the second C2 domain. Unlike most other synaptotagmins it is nearly absent in the brain and rather is found in the heart, lungs, skeletal muscle, and testis. Synaptotagmin 17 is located in the brain, kidney, and prostate and is thought to be a peripheral membrane protein. Previously all synaptotagmins were thought to be calcium sensors in the regulat

>cd04037 C2E_Ferlin C2 domain fifth repeat in Ferlin. Ferlins are involved in vesicle fusion events. Ferlins and other proteins, such as Synaptotagmins, are implicated in facilitating the fusion process when cell membranes fuse together. There are six known human Ferlins: Dysferlin (Fer1L1), Otoferlin (Fer1L2), Myoferlin (Fer1L3), Fer1L4, Fer1L5, and Fer1L6. Defects in these genes can lead to a wide range of diseases including muscular dystrophy (dysferlin), deafness (otoferlin), and infertility (fer-1, fertilization factor-1). Structurally they have 6 tandem C2 domains, designated as (C2A-C2F) and a single C-terminal transmembrane domain, though there is a new study that disputes this and claims that there are actually 7 tandem C2 domains with another C2 domain inserted between C2D and C2E. In a subset of them (Dysferlin, Myoferlin, and Fer1) there is an additional conserved domain called DysF. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangemen

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.

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. 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

>PF00168 C2: C2 domain; InterPro: IPR000008 The C2 domain is a Ca2+-dependent membrane-targeting module found in many cellular proteins involved in signal transduction or membrane trafficking. C2 domains are unique among membrane targeting domains in that they show wide range of lipid selectivity for the major components of cell membranes, including phosphatidylserine and phosphatidylcholine. This C2 domain is about 116 amino-acid residues and is located between the two copies of the C1 domain in Protein Kinase C (that bind phorbol esters and diacylglycerol) (see PDOC00379 from PROSITEDOC) and the protein kinase catalytic domain (see PDOC00100 from PROSITEDOC). Regions with significant homology [] to the C2-domain have been found in many proteins. The C2 domain is thought to be involved in calcium-dependent phospholipid binding [] and in membrane targetting processes such as subcellular localisation. The 3D structure of the C2 domain of synaptotagmin has been reported [], the domain forms an eight-stranded beta sandwich constructed around a conserved 4-stranded motif, designated a C2 key []. Calcium binds in a cup-shaped depression formed by the N- and C-terminal loops of the C2-key motif. Structural analyses of several C2 domains have shown them to consist of similar ternary structures in which three Ca2+-binding loops are located at the end of an 8 stranded antiparallel beta sandwich. ; GO: 0005515 protein binding; PDB: 1RSY_A 1BYN_A 3NSJ_A 3QR1_D 3HN8_C 1DQV_A 3M7F_B 3KWU_A 3KWT_A 1V27_A ....

>cd04043 C2_Munc13_fungal C2 domain in Munc13 (mammalian uncoordinated) proteins; fungal group. C2-like domains are thought to be involved in phospholipid binding in a Ca2+ independent manner in both Unc13 and Munc13. Caenorabditis elegans Unc13 has a central domain with sequence similarity to PKC, which includes C1 and C2-related domains. Unc13 binds phorbol esters and DAG with high affinity in a phospholipid manner. Mutations in Unc13 results in abnormal neuronal connections and impairment in cholinergic neurotransmission in the nematode. Munc13 is the mammalian homolog which are expressed in the brain. There are 3 isoforms (Munc13-1, -2, -3) and are thought to play a role in neurotransmitter release and are hypothesized to be high-affinity receptors for phorbol esters. Unc13 and Munc13 contain both C1 and C2 domains. There are two C2 related domains present, one central and one at the carboxyl end. Munc13-1 contains a third C2-like domain. Munc13 interacts with syntaxin, synap

Kibra is thought to be a regulator of the Salvador (Sav)/Warts (Wts)/Hippo (Hpo) (SWH) signaling network, which limits tissue growth by inhibiting cell proliferation and promoting apoptosis. The core of the pathway consists of a MST and LATS family kinase cascade that ultimately phosphorylates and inactivates the YAP/Yorkie (Yki) transcription coactivator. The FERM domain proteins Merlin (Mer) and Expanded (Ex) are part of the upstream regulation controlling pathway mechanism. Kibra colocalizes and associates with Mer and Ex and is thought to transduce an extracellular signal via the SWH network. The apical scaffold machinery that contains Hpo, Wts, and Ex recruits Yki to the apical membrane facilitating its inhibitory phosphorlyation by Wts. Since Kibra associates with Ex and is apically located it is hypothesized that KIBRA is part of the scaffold, helps in the Hpo/Wts complex, and helps recruit Yki for inactivation that prom

>cd08692 C2B_Tac2-N C2 domain second repeat found in Tac2-N (Tandem C2 protein in Nucleus). Tac2-N contains two C2 domains and a short C-terminus including a WHXL motif, which are key in stabilizing transport vesicles to the plasma membrane by binding to a plasma membrane. However unlike the usual carboxyl-terminal-type (C-type) tandem C2 proteins, it lacks a transmembrane domain, a Slp-homology domain, and a Munc13-1-interacting domain. Homology search analysis indicate that no known protein motifs are located in its N-terminus, making Tac2-N a novel class of Ca2+-independent, C-type tandem C2 proteins. 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 polypho

>cd08374 C2F_Ferlin C2 domain sixth repeat in Ferlin. Ferlins are involved in vesicle fusion events. Ferlins and other proteins, such as Synaptotagmins, are implicated in facilitating the fusion process when cell membranes fuse together. There are six known human Ferlins: Dysferlin (Fer1L1), Otoferlin (Fer1L2), Myoferlin (Fer1L3), Fer1L4, Fer1L5, and Fer1L6. Defects in these genes can lead to a wide range of diseases including muscular dystrophy (dysferlin), deafness (otoferlin), and infertility (fer-1, fertilization factor-1). Structurally they have 6 tandem C2 domains, designated as (C2A-C2F) and a single C-terminal transmembrane domain, though there is a new study that disputes this and claims that there are actually 7 tandem C2 domains with another C2 domain inserted between C2D and C2E. In a subset of them (Dysferlin, Myoferlin, and Fer1) there is an additional conserved domain called DysF. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangemen

>cd04033 C2_NEDD4_NEDD4L 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 arrangemen

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).

>cd08686 C2_ABR C2 domain in the Active BCR (Breakpoint cluster region) Related protein. The ABR protein is similar to the breakpoint cluster region protein. It has homology to guanine nucleotide exchange proteins and GTPase-activating proteins (GAPs). ABR is expressed primarily in the brain, but also includes non-neuronal tissues such as the heart. It has been associated with human diseases such as Miller-Dieker syndrome in which mental retardation and malformations of the heart are present. ABR contains a RhoGEF domain and a PH-like domain upstream of its C2 domain and a RhoGAP domain downstream of this domain. A few members also contain a Bcr-Abl oncoprotein oligomerization domain at the very N-terminal end. Splice variants of ABR have been identified. ABR is found in a wide variety of organisms including chimpanzee, dog, mouse, rat, fruit fly, and mosquito. The C2 domain was first identified in PKC.

>PF10347 Fmp27_GFWDK: RNA pol II promoter Fmp27 protein domain; InterPro: IPR019441 This domain is found in fungi, metazoans and plants that contains a characteristic GFWDK sequence motif. These include FMP27 and maize protein APT1 and Arabidopsis homologues SABRE and KIP. The function of the FMP27 protein is not known. FMP27 is the product of a nuclear encoded gene but it is detected in highly purified mitochondria in high-throughput studies []. APT1 is required for pollen tube growth. It is a Golgi-localised protein and appears to regulate vesicular trafficking []. SABRE and KIP are APT1 homologues and they are involved in the elongation of root cortex cells and pollen tubes respectively.

>cd04010 C2B_RasA3 C2 domain second repeat present in RAS p21 protein activator 3 (RasA3). RasA3 are members of GTPase activating protein 1 (GAP1), a Ras-specific GAP, 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. RasA3 contains an N-terminal C2 domain, a Ras-GAP domain, a plextrin homology (PH)-like domain, and a Bruton's Tyrosine Kinase (BTK) zinc binding domain. 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
