Probable UDP-glucose transmembrane transporter involved in UDP-glucose transport from the cytosol to the lumen of synaptic vesicles . It is involved in platelet dense granules maturation (By similarity).
Alternatively, could function as a molecular adapter enhancing the formation of the PI3KC3-C1/AIC/autophagy initiation complex to promote autophagy in dopaminergic neurons. Could also regulate the plasma membrane localization of the D(1A) dopamine receptor/DRD1 and dopamine signaling.
Subcellular locations: Cytoplasmic vesicle, Secretory vesicle, Synaptic vesicle membrane, Early endosome membrane, Endoplasmic reticulum membrane
Active at early endosome membrane in the biosynthesis of mature platelet-dense granules.
