资源简介:
RAB8A is another small GTPase that is required for ciliogenesis. RAB8A is recruited to the ciliary targeting complex at the trans-Golgi network (TGN) through interactions of the RAB8A guanine nucleotide exchange factor (GEF) RAB3IP (also known as RABIN8) with ASAP1 and RAB11 (Wang et al, 2012; Westlake et al, 2011; Feng et al, 2012; reviewed in Deretic, 2013). RAB8A is recruited in the inactive GDP bound form, and is activated at the TGN by RAB3IP in a RAB11A-dependent fashion (Hatulla et al, 2002; Knodler et al, 2010; Westlake et al, 2012; Wang et al, 2012; Feng et al, 2012).
RAB8A 为另一种必需参与鞭毛发生的小型 GTP 酶。RAB8A 通过 RAB8A 鸟苷酸交换因子(GEF)RAB3IP(亦称 RABIN8)与 ASAP1 及 RAB11 的相互作用,被招募至转高尔基网络(TGN)的鞭毛靶向复合物中(Wang 等人,2012;Westlake 等人,2011;Feng 等人,2012;参见 Deretic,2013 年综述)。RAB8A 以非活性 GDP 结合形式被招募,并通过 RAB3IP 在 TGN 中以 RAB11A 依赖性方式被激活(Hatulla 等人,2002;Knodler 等人,2010;Westlake 等人,2012;Wang 等人,2012;Feng 等人,2012)。
