该基因编码的蛋白是一种GTPase，属于小GTP结合蛋白RAS超家族这个超家族的成员似乎调节了一系列不同的细胞事件，包括控制细胞生长、细胞骨架重组和激活蛋白激酶选择性剪接导致多个转录变体[由RefSeq提供，2015年10月]
The protein encoded by this gene is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2015]
