RAB3A (P20336) - Overview - Molecular Target Synopsis


RAB3A, Ras-related protein Rab-3A
UniProt P20336

Also Known as RAB3A_HUMAN, RAB3A

Involved in exocytosis by regulating a late step in synaptic vesicle fusion. Could play a role in neurotransmitter release by regulating membrane flow in the nerve terminal. Heterodimer with RIMS2. Part of a ternary complex involving PCLO and EPAC2. Interacts with RPH3A and RPH3AL. Interacts with the exocyst complex through SEC15. Binds SYTL4 and RIMS1. Interacts with RAB3IP. Interacts with SGSM1 and SGSM3.
