Seems not to activate RAB3A. Involved in cAMP-dependent, PKA- independent exocytosis through interaction with RIMS2 (By similarity). {ECO:0000250, ECO:0000269|PubMed:10777494, ECO:0000269|PubMed:9856955}. |DEP| |RasGEF| |cNMP binding| |RasGEF N| |Ras GTPase binding| |Ras guanyl-nucleotide exchange factor activity| |cAMP binding| |hippocampal mossy fiber to CA3 synapse| |insulin secretion| |calcium-ion regulated exocytosis| |peptide hormone secretion| |hormone secretion| |hormone transport| |guanyl-nucleotide exchange factor activity| |regulation of synaptic vesicle cycle| |cAMP-mediated signaling| |protein secretion| |establishment of protein localization to extracellular region| |protein localization to extracellular region| |signal release| |cyclic-nucleotide-mediated signaling| |peptide secretion| |regulation of insulin secretion| |regulation of peptide hormone secretion| |regulation of exocytosis| |regulation of hormone secretion| |small GTPase mediated signal transduction| |second-messenger-mediated signaling| |regulation of protein secretion| |regulation of peptide secretion| |regulation of hormone levels| |regulation of vesicle-mediated transport| |regulated exocytosis| |regulation of protein transport| |regulation of peptide transport| |regulation of establishment of protein localization| |regulation of secretion by cell| |exocytosis| |regulation of secretion| |regulation of cellular localization| |secretion by cell| |regulation of protein localization| |export from cell| |cell-cell signaling| |secretion| |G protein-coupled receptor signaling pathway| |protein transport| |peptide transport| |amide transport| |establishment of protein localization| |intracellular signal transduction| |nitrogen compound transport| |regulation of transport| |vesicle-mediated transport| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp273|Cisplatin 0.35μM R06 exp273]]|-1.7| |[[:results:exp530|Thioridazine 5μM R08 exp530]]|1.72| |[[:results:exp473|Cincreasin 100μM R08 exp473]]|1.81| |[[:results:exp249|Vinorelbine 0.001μM R05 exp249]]|1.91| |[[:results:exp447|Amiloride 100μM R08 exp447]]|1.94| |[[:results:exp454|Bafilomycin-A1 0.009μM R08 exp454]]|2.34| No correlation found to any other genes in chemogenomics.
