Rab3gap1 - RAB3 GTPase activating protein subunit 1

Predicted to enable GTPase activator activity and small GTPase binding activity. Predicted to contribute to guanyl-nucleotide exchange factor activity. Involved in several processes, including excitatory postsynaptic potential; modulation of chemical synaptic transmission; and positive regulation of GTPase activity. Predicted to be located in several cellular components, including endoplasmic reticulum tubular network; excitatory synapse; and lipid droplet. Predicted to be part of protein-containing complex. Is expressed in several structures, including brain and neural retina. Human ortholog(s) of this gene implicated in Warburg micro syndrome 1. Orthologous to human RAB3GAP1 (RAB3 GTPase activating protein catalytic subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
