蛋白质信息 (UniProt)

Rho鸟嘌呤核苷酸交换因子25 (鸟嘌呤核苷酸交换因子GEFT) (Rac/Cdc42/Rho交换因子GEFT) (RhoA/Rac/Cdc42鸟嘌呤核苷酸交换因子GEFT) (p63RhoGEF)

Q86VW2

功能描述

可能在不同组织的肌动蛋白细胞骨架重组中发挥作用,因为其激活诱导肌动蛋白应力纤维的形成。它作为Rho家族小GTP酶的鸟嘌呤核苷酸交换因子。特异性连接G alpha q/11偶联受体与RHOA激活。可能是轴突和树突形成过程的重要调节因子。在神经元中似乎主要是RAC1的交换因子。参与骨骼肌发生(通过相似性)。{ECO:0000250, ECO:0000269|PubMed:11861769, ECO:0000269|PubMed:12547822, ECO:0000269|PubMed:15069594, ECO:0000269|PubMed:15632174, ECO:0000269|PubMed:16314529, ECO:0000269|PubMed:17606614}。

组织特异性

Isoform 1 and isoform 2 are highly expressed in excitable tissues, such as brain, heart and muscle. Also detected in kidney and liver.
