Rac gtpase是什么

Rac is a subfamily of the Rho family of GTPases, small (~21 kDa) signaling G proteins (more specifically a GTPase). Just as other G proteins, Rac acts as a molecular switch, remaining inactive while bound to GDP and activated once GEFs remove GDP, permitting GTP to bind. When bound to GTP, Rac is activated. In its activated state, Rac participates in the regulation of cell movement, through its involvement in structural changes to the actin Cytoskeleton. By changing … TīmeklisRac 家族小 GTPase 2： 该基因编码小鸟苷三磷酸 (GTP) 代谢蛋白 Ras 超家族的成员。编码的蛋白质定位于质膜，在那里它调节多种过程，例如分泌、吞噬作用和细胞极化 …
