Tissue Specificity | Specifically expressed in brain. |
Post Translational Modifications | Ubiquitinated. Deubiquitinated by CAND1 to prevent its degradation. |
Function | Plays an essential role in docking and fusion steps of regulated exocytosis. At the presynaptic level, RPH3A is recruited by RAB3A to the synaptic vesicle membrane in a GTP-dependent manner where it modulates synaptic vesicle trafficking and calcium-triggered neurotransmitter release. In the post-synaptic compartment, forms a ternary complex with GRIN2A and DLG4 and regulates NMDA receptor stability. Also plays a role in the exocytosis of arginine vasopressin hormone. |
