Facts about Small G protein signaling modulator 2.
Possesses GTPase activator activity towards RAB32, RAB33B and RAB38 (PubMed:26620560, PubMed:21808068).
Regulates the trafficking of melanogenic enzymes TYR, TYRP1 and DCT/TYRP2 to melanosomes in melanocytes by inactivating RAB32 and RAB38.Inhibits RAB32 and RAB38 activation both directly by boosting their GTPase activity and indirectly by disrupting the RAB9A-HPS4 interaction that's needed for RAB32/38 activation (PubMed:26620560). .
