RHOT2 GTPase cycle

Reactome ID: R-HSA-9013419

中文名称

RHOT2 GTPase 循环

通路描述

该通路收录了 RHOT2 的鸟苷酸交换因子 (GEFs) 和 RHOT2 的效应子 (也称为 MIRO-2)。RHOT2 具有内在的高 GTP 酶活性,不需要 GTP 酶激活蛋白 (GAP) (Peters et al. 2018)。尚未报道与 RHOT2 相互作用的 GDP 解离抑制剂 (GDIs)。RHOT2 是一种线粒体 RHO GTP 酶。与相关的 RHOT1 (MIRO-1) 类似,RHOT2 定位于外膜。与 RHOT1 类似,RHOT2 通过耦合线粒体与驱动其沿微管运输的驱动蛋白和动力蛋白来调节线粒体的运动 (Devine et al. 2016)。RHOT2 还定位于过氧化物酶体,并参与过氧化物酶体动力学 (Covill-Cooke et al. 2020)。
英文描述
RHOT2 GTPase cycle This pathway catalogues guanine nucleotide exchange factors (GEFs) and effectors of RHOT2 (also known as MIRO-2). RHOT2 possesses a high intrinsic GTP-ase activity and does not require a GTPase activator protein (GAP) (Peters et al. 2018). No GDP dissociation inhibitors (GDIs) have been reported to interact with RHOT2. RHOT2 is a mitochondrial RHO GTPase. Like related RHOT1 (MIRO-1), RHOT2 localizes to the outer mitochondrial membrane. Similar to RHOT1, RHOT2 regulates mitochondrial movement by coupling mitochondria to kinesin and dynein motors that transport them along microtubules (Devine et al. 2016). RHOT2 is also localized to peroxisomes and it is involved in peroxisomal dynamics (Covill-Cooke et al. 2020).
