== Function Summary ==
* **Entrez Summary**: 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].
* **UniProt Summary**: 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). {ECO:0000269|PubMed:21808068, ECO:0000269|PubMed:26620560}.
