Biological function summary
Rab3A facilitates neurotransmitter release by interacting with effector proteins such as RIM and Rabphilin-3A. It is part of a larger complex that includes the SNAREs which help mediate synaptic vesicle fusion. Through its regulatory action Rab3A ensures that neurotransmitters are released in a controlled manner during synaptic transmission which is essential for proper neuronal communication.
Pathways
Rab3A participates in the synaptic vesicle cycle which is vital in neurotransmitter release. This cycle involves key proteins like Syntaxin and VAMP. Rab3A interacts with these SNARE proteins to participate in vesicle docking and priming. Additionally it plays a role in the calcium-dependent exocytosis pathway which relies on calcium ions triggering vesicle fusion at nerve terminals.

常规信息
功能
The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes (PubMed : 2501306). Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion (PubMed : 2501306). RAB3A plays a central role in regulated exocytosis and secretion. Controls the recruitment, tethering and docking of secretory vesicles to the plasma membrane (PubMed : 2501306). 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 (PubMed : 27325790). Acts as a positive regulator of acrosome content secretion in sperm cells by interacting with RIMS1 (PubMed : 22248876, PubMed : 30599141). Also plays a role in the regulation of dopamine release by interacting with synaptotagmin I/SYT (By similarity).
序列相似性
Belongs to the small GTPase superfamily. Rab family.
翻译后修饰
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.
