ADP Ribosylation Factor Related Protein 1; ARF-Related Protein 1; ARP1; ARP; ADP-Ribosylation Factor-Related Protein 1; Helicase-Like Protein NHL; SCG10 Like-Protein; ARL18

The protein encoded by this gene is a membrane-associated GTP-ase which localizes to the plasma membrane and is related to the ADP-ribosylation factor (ARF) and ARF-like (ARL) proteins. This gene plays a role in membrane trafficking between the trans-Golgi network and endosomes. Alternatively spliced transcript variants encoding different isoforms have been identified.
