| 产品介绍 | 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. The protein encoded by this gene is prenylated at its C-terminus, and localizes to the cytoplasm and plasma membrane. It is thought to be important in cell locomotion. Overexpression of this gene is associated with tumor cell proliferation and metastasis. Multiple alternatively spliced variants, encoding the same protein, have been identified. Subunit: nteracts with RGNEF. Binds PRKCL1, ROCK1 and ROCK2. Interacts with ARHGEF2, ARHGEF3, NET1 and RTKN. Interacts with PLCE1 and AKAP13. Interacts (in the constitutively activated, GTP-bound form) with DGKQ. Interacts with human respiratory syncytial virus (HRSV) protein F; this interaction facilitates virus-induced syncytium formation. Interacts with GNB2L1/RACK1; enhances RHOA activation. Interacts with PKP4; the interaction is detected at the midbody. Interacts (GTP-bound form preferentially) with PKN2; the interaction stimulates autophosphorylation and phosphorylation of PKN2. Similarity: Belongs to the small GTPase superfamily. Rho family.

RhoA蛋白主要分布在细胞质和细胞膜,RhoA蛋白家族是控制细胞骨架蛋白组合、调节基因表达等细胞活动过程中的关键信号转导成分。通常,RhoA通过激活其下游的Rho 连接激酶(Rho associated kinase,ROK)而起作用。在调节细胞骨架组建的过程中,RhoA与其作用对象均在胞质内。 |

文献和实验有关。 TCR-pMHC信号转导通过T细胞骨架蛋白重排诱导免疫突触形成 首先涉及左下方的肌动蛋白多聚化调节分子RhoA,这是TCR识别MHC提呈的抗原肽后,借助蛋白酪氨酸激酶Fyn和Lck等激活ZAP-70,后者且通过IrAT招募SLP-76和NCK等一系列衔接蛋白,使鸟苷酸置换因子Vavl磷酸化后所激活的主要分子。二是LFA-1分子胞内段可结合一种连接质膜与细胞骨架的踝蛋白(Talin)的分子,共同参与肌动蛋白构型的变更。另外微管组织中心(MTOS)对微管装配的调节,也可改变胞内的细胞
阿兰梦 看了文献测活性RhoA 有几种方法: 1、经典的,是放射标记γ32-P-GTP 方法,因为放射性,现在不怎么用了。 2、看到国内有文献,采用分离胞膜胞浆,然后用抗RhoA抗体做western。这是基于胞浆都是GDP-RhoA,胞膜是GTP-RhoA的原理,但是总觉得有什么不对的地方?为什么没有被广泛采用? 3、现在多采用 pull down方法,RhoA-GTP与Rhotekin的RBD结合,最后
NCB | 管坤良课题组揭示 Hippo 信号通路活化机制,为肿瘤治疗提供新靶点
由于与机体发育、器官大小调控、组织稳态和肿瘤发生密切相关,近些年来,关于 Hippo 信号通路的研究也越来越受到重视。先前的研究表明,Hippo 信号通路实质上是一个激酶级联反应介导的生长抑制信号通路。在感知多种信号刺激时,比如细胞连接、细胞极化、血清饥饿和溶血磷脂酸(LPA)缺乏,Hippo 信号通路中的关键激酶 MST1 / 2 和 MAP4Ks 会磷酸化活化 LATS1 / 2 激酶,后者诱导 YAP/TAZ 磷酸化,抑制 YAP/TAZ 入核启动靶标基因表达,从而阻断 YAP 的促生长
