The protein encoded by this gene is a GTPase activator with activity towards RAB32 and RAB33B, which are regulators of membrane trafficking. The encoded protein inactivates RAB32 and can bind RAB9A-GTP, a protein required for RAB32 activation. [provided by RefSeq, Oct 2016]
GeneCards Summary for SGSM2 Gene
SGSM2 (Small G Protein Signaling Modulator 2) is a Protein Coding gene. Gene Ontology (GO) annotations related to this gene include GTPase activator activity and Rab GTPase binding. An important paralog of this gene is SGSM1.
UniProtKB/Swiss-Prot for SGSM2 Gene
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 promoting their GTPase activity and indirectly by disrupting the RAB9A-HPS4 interaction which is required for RAB32/38 activation (PubMed:26620560).
