Plays a role in short-term synaptic plasticity in a subset of GABAergic neurons in the brain.
Subcellular locations: Cytoplasmic vesicle membrane, Cell membrane, Cell projection, Dendrite, Cytoplasmic vesicle, Secretory vesicle, Synaptic vesicle membrane, Cell projection, Growth cone membrane, Early endosome membrane, Recycling endosome, Endoplasmic reticulum-Golgi intermediate compartment membrane, Endosome membrane
Recycles from the vesicles of the endocytic recycling compartment (ERC) to the plasma membrane (By similarity). Colocalizes with UNC93B1 in large endosomal intracellular vesicles (By similarity). Accumulates in the endoplasmic reticulum-Golgi intermediate compartment (ERGIC) before its disappearance upon activation by CpG dinucleotides (By similarity). Associates with cortical membranes (By similarity). Localizes mostly in cytoplasmic vesicles of neuronal cell body. Localizes to synaptic vesicles in a subset of GABAergic neurons (By similarity).
