该基因编码的蛋白是一种膜相关gtp酶，定位于质膜，与adp核糖基化因子（arf）和arf样蛋白（arl）有关。这个基因在跨高尔基体网络和内切体之间的膜运输中起作用。另外，还发现了编码不同亚型的剪接转录变体。[由RefSeq提供，2012年5月]
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.
