Previous Symbols for ARFGAP3 Gene
The protein encoded by this gene is a GTPase-activating protein (GAP) that associates with the Golgi apparatus and regulates the early secretory pathway of proteins. The encoded protein promotes hydrolysis of ADP-ribosylation factor 1 (ARF1)-bound GTP, which is required for the dissociation of coat proteins from Golgi-derived membranes and vesicles. Dissociation of the coat proteins is a prerequisite for the fusion of these vesicles with target compartments. The activity of this protein is sensitive to phospholipids. Multiple transcript variants encoding different isoforms have been found for this gene. This gene was originally known as ARFGAP1, but that is now the name of a related but different gene.

GeneCards Summary for ARFGAP3 Gene
ARFGAP3 (ADP-Ribosylation Factor GTPase Activating Protein 3) is a Protein Coding gene. Among its related pathways are GPCR Pathway and PAK Pathway. GO annotations related to this gene include protein transporter activity. An important paralog of this gene is ARFGAP2.
UniProtKB/Swiss-Prot for ARFGAP3 Gene
GTPase-activating protein (GAP) for ADP ribosylation factor 1 (ARF1). Hydrolysis of ARF1-bound GTP may lead to dissociation of coatomer from Golgi-derived membranes to allow fusion with target membranes.
Small G proteins (small GTPases) are homologous to Galpha proteins and are often referred to as the Ras proto-oncogene superfamily. The Ras superfamily contains over 100 small GTPases grouped into eight families; Ras, Rho, Rab, Rap, Arf, Ran, Rheb and Rad. Small GTPases regulate a wide variety of processes in the cell, including growth, differentiation, movement and lipid vesicle transport.
