Overview:
RhoA is a member of the Rho gene family that interacts with protein kinases and serves as a target of activated GTPase. RhoA play an important role in the initial events of cell protrusion, whereas Rac1 and Cdc42 activate pathways implicated in reinforcement and stabilization of newly expanded protrusions. Rho mediates corneal epithelial migration in response to external stimuli by regulating the organization of the actin cytoskeleton (1). The inhibition of RhoA signaling is required for both vaccinia morphogenesis and virus-induced cell motility. Vaccinia inhibits RhoA signalling using the viral protein F11 and this can enhance the spread of infection (2).
Gene Aliases:
ARH12; ARHA; RHO12; RHOH12

提RNA一般注意:提取前材料的保存(新鲜材料,过夜处理的样品),提取中对外源性的RNA酶的清除控制(离心管,PCR管,电泳槽,台面等的无RNA酶化处理),提取后需要-80度保存.其次跑电泳时,注意电泳液最好用新鲜的,核酸染料等诸多因素.

对于外源性RNA酶的控制外源RNA酶清除剂,避免使用致癌物DEPC的危险方法就可简单操作清除耗材,台面,仪器等的外源RNA酶的降解作用.
