======= DOC2B ======= == Gene Information == * **Official Symbol**: DOC2B * **Official Name**: double C2 domain beta * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=8447|8447]] * **UniProt**: [[https://www.uniprot.org/uniprot/Q14184|Q14184]] * **Interactions**: [[https://thebiogrid.org/search.php?search=DOC2B&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20DOC2B|Open PubMed]] * **OMIM**: [[https://omim.org/entry/604568|Open OMIM]] == Function Summary == * **Entrez Summary**: There are at least two protein isoforms of the Double C2 protein, namely alpha (DOC2A) and beta (DOC2B), which contain two C2-like domains. DOC2A and DOC2B are encoded by different genes; these genes are at times confused with the unrelated DAB2 gene which was initially named DOC-2. DOC2B is expressed ubiquitously and is suggested to be involved in Ca(2+)-dependent intracellular vesicle trafficking in various types of cells. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: Calcium sensor which positively regulates SNARE- dependent fusion of vesicles with membranes. Binds phospholipids in a calcium-dependent manner and may act at the priming stage of fusion by modifying membrane curvature to stimulate fusion. Involved in calcium-triggered exocytosis in chromaffin cells and calcium-dependent spontaneous release of neurotransmitter in absence of action potentials in neuronal cells. Involved both in glucose-stimulated insulin secretion in pancreatic cells and insulin-dependent GLUT4 transport to the plasma membrane in adipocytes (By similarity). {ECO:0000250, ECO:0000269|PubMed:9804756}. |C2| |spontaneous neurotransmitter secretion| |spontaneous synaptic transmission| |positive regulation of vesicle fusion| |calcium ion-regulated exocytosis of neurotransmitter| |positive regulation of calcium ion-dependent exocytosis| |regulation of vesicle fusion| |calcium-ion regulated exocytosis| |regulation of calcium ion-dependent exocytosis| |SNARE complex| |positive regulation of regulated secretory pathway| |syntaxin binding| |calcium-dependent phospholipid binding| |synaptic vesicle exocytosis| |positive regulation of insulin secretion| |positive regulation of exocytosis| |presynapse| |positive regulation of peptide hormone secretion| |signal release from synapse| |neurotransmitter secretion| |synaptic vesicle cycle| |positive regulation of hormone secretion| |vesicle-mediated transport in synapse| |regulation of regulated secretory pathway| |signal release| |regulation of insulin secretion| |neurotransmitter transport| |regulation of peptide hormone secretion| |regulation of exocytosis| |regulation of hormone secretion| |positive regulation of protein secretion| |positive regulation of peptide secretion| |regulation of neurotransmitter levels| |positive regulation of secretion by cell| |anterograde trans-synaptic signaling| |chemical synaptic transmission| |positive regulation of protein transport| |positive regulation of secretion| |trans-synaptic signaling| |positive regulation of establishment of protein localization| |synaptic signaling| |regulation of protein secretion| |regulation of peptide secretion| |regulation of hormone levels| |regulation of vesicle-mediated transport| |positive regulation of organelle organization| |regulated exocytosis| |regulation of protein transport| |calcium ion binding| |regulation of peptide transport| |regulation of establishment of protein localization| |regulation of secretion by cell| |exocytosis| |regulation of secretion| |positive regulation of transport| |secretion by cell| |regulation of protein localization| |export from cell| |cell-cell signaling| |secretion| |positive regulation of cellular component organization| |regulation of organelle organization| |positive regulation of cell communication| |positive regulation of signaling| |establishment of localization in cell| |regulation of transport| |vesicle-mediated transport| \\ === CRISPR Data === No hits were found.
