Research Backgrounds

Function:

Small GTP-binding protein that plays a central role in regulated exocytosis and secretion. Controls the recruitment, tethering and docking of secretory vesicles to the plasma membrane (By similarity). Upon stimulation, switches to its active GTP-bound form, cycles to vesicles and recruits effectors such as RIMS1, RIMS2, Rabphilin-3A/RPH3A, RPH3AL or SYTL4 to help the docking of vesicules onto the plasma membrane (By similarity). Upon GTP hydrolysis by GTPase-activating protein, dissociates from the vesicle membrane allowing the exocytosis to proceed (By similarity). Stimulates insulin secretion through interaction with RIMS2 or RPH3AL effectors in pancreatic beta cells (By similarity). Regulates calcium-dependent lysosome exocytosis and plasma membrane repair (PMR) via the interaction with 2 effectors, SYTL4 and myosin-9/MYH9. Acts as a positive regulator of acrosome content secretion in sperm cells by interacting with RIMS1. Plays also a role in the regulation of dopamine release by interacting with synaptotagmin I/SYT (By similarity).

PTMs:

Phosphorylation of Thr-86 in the switch II region by LRRK2 prevents the association of RAB regulatory proteins, including CHM, CHML and RAB GDP dissociation inhibitors GDI1 and GDI2.

Tissue Specificity:

Specifically expressed in brain.

Subunit Structure:

Interacts with RIMS1 and RIMS2 (By similarity). Interacts with Rabphilin-3A/RPH3A and Rab effector Noc2/RPH3AL (By similarity). Interacts with SYTL4 (By similarity). Interacts with RAB3IP (By similarity). Interacts with SGSM1 and SGSM3 (By similarity). Interacts with SYT1 (By similarity). Interacts with MYH9; this interaction is essential for lysosome exocytosis and plasma membrane repair. Interacts with STXBP1; this interaction promotes RAB3A dissociation from the vesicle membrane (By similarity). Interacts with SNCA. Interacts with GDI1, GDI2, CHM and CHML; phosphorylation at Thr-86 disrupts these interactions.

Family&Domains:

Belongs to the small GTPase superfamily. Rab family.
