Anti-Rab3A antibodies shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab3335 and ab302518 were shown to bind specifically to RAB3A. A band was observed at 27 kDa in wild-type SK-N-FI cell lysates with no signal observed at this size in RAB3A knockout cell line. To generate this image, wild-type and RAB3A knockout SK-N-FI cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3% milk in TBS-0.1% Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Supplementary information

Rab3A also known as Ras-related protein Rab-3A acts as a small GTPase involved in regulating membrane trafficking. Its molecular mass is approximately 25 kDa. Rab3A is highly expressed in neurons particularly at synaptic vesicles. It cycles between an active GTP-bound state and an inactive GDP-bound state to regulate the docking and fusion of synaptic vesicles with the presynaptic membrane.
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.

Rab3A associates with neurological conditions such as epilepsy and synaptic dysfunction. Dysfunction in Rab3A mechanisms can lead to improper neurotransmitter release and synaptic connectivity contributing to these conditions. The protein links to diseases through its interactions with proteins such as RIM which can also affect synaptic function and are implicated in certain neurodevelopmental disorders.

Target data

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).
