该基因编码rhoGAP蛋白家族的一个成员，该家族在一些细胞过程中调节肌动蛋白在质膜上的聚合这种蛋白被认为有两种独立的功能，一种是对RhoA有特异性的GTPase激活蛋白，另一种是促进肌动蛋白重塑的细胞骨架蛋白已经发现该基因的多个交替剪接的转录变体编码不同的亚型。[由RefSeq提供，2008年7月]
This gene encodes a member of the rhoGAP family of proteins which play a role in the regulation of actin polymerization at the plasma membrane during several cellular processes. This protein is thought to have two independent functions, one as a GTPase-activating protein with specificity for RhoA, and another as a cytoskeletal protein that promotes actin remodeling. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
