RIMS1 Rab effector involved in exocytosis. May act as scaffold protein that regulates neurotransmitter release at the active zone. Essential for maintaining normal probability of neurotransmitter release and for regulating release during short-term synaptic plasticity. Plays a role in dendrite formation by melanocytes. Expressed in melanocytes (PubMed:23999003). Detected in brain and retina (PubMed:23999003). 13 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
