Enables GTP binding activity. Predicted to be involved in intracellular protein transport and vesicle-mediated transport. Predicted to act upstream of or within brown fat cell differentiation. Located in cytosol; nuclear lumen; and plasma membrane.
RGD Description
ADP-ribosylation factor-like 4A is a member of the ADP-ribosylation factor family of GTP-binding proteins. ARL4A is similar to ARL4C and ARL4D and each has a nuclear localization signal and an unusually high guaninine nucleotide exchange rate. ARL4A is located in both the nuclear and extranuclear cell compartments. Multiple transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]
