DESCRIPTION

Also known as ARL1_HUMAN, ARL1. GTP-binding protein that recruits several effectors, such as golgins, arfaptins and Arf-GEFs to the trans-Golgi network, and modulates their functions at the Golgi complex (PubMed:9624189, PubMed:21239483, PubMed:27436755, PubMed:22679020, PubMed:27373159). Plays thereby a role in a wide range of fundamental cellular processes, including cell polarity, innate immunity, or protein secretion mediated by arfaptins, which were shown to play a role in maintaining insulin secretion from pancreatic beta cells (PubMed:22981988). The GTP-bound form interacts with GOLGA1 (By similarity). The GTP-bound form interacts with GOLGA4 and RGPD8. The GTP-bound form directly interacts with ARFIP2 (PubMed:11303027, PubMed:21239483, PubMed:22679020). Binds to SCOC, preferentially in its GTP-bound form. May interact with UNC119 (PubMed:11303027, PubMed:14580338). Interacts with ARFIP1; this interaction directs ARFIP1 to the trans-Golgi membranes (PubMed:21239483, PubMed:22981988). Interacts with ARFGEF1 (via N-terminus) (PubMed:27436755, PubMed:27373159).
