RHOA

这个基因编码一个小GTP酶的rho家族成员，在非活性GDP结合态和活性GTP结合态之间循环，在信号转导级联中起分子开关的作用。rho蛋白促进肌动蛋白细胞骨架的重组并调节细胞的形状、附着和运动。该基因的过度表达与肿瘤细胞增殖和转移有关。已识别出多个可选拼接变体。
This gene encodes a member of the Rho family of small GTPases, which cycle between inactive GDP-bound and active GTP-bound states and function as molecular switches in signal transduction cascades. Rho proteins promote reorganization of the actin cytoskeleton and regulate cell shape, attachment, and motility. Overexpression of this gene is associated with tumor cell proliferation and metastasis. Multiple alternatively spliced variants have been identified.
