Supplementary information

RhoA also known as Ras homolog family member A is a small signaling GTPase. It weighs approximately 21 kDa. This protein is a part of the Rho family which includes other members like RhoB and RhoC. RhoA is widely expressed in various tissues including the brain kidney liver and lungs. Mechanically RhoA functions as a molecular switch cycling between an active GTP-bound state and an inactive GDP-bound state. This activity regulates the organization of the actin cytoskeleton and influences cell shape attachment and motility.
Biological function summary

The role of RhoA extends to cell proliferation and differentiation. It is a component of the Rho-GTPase cycle interacting with numerous effectors to transmit signals from the cell membrane to the actin cytoskeleton. RhoA influences the assembly of stress fibers and focal adhesions. It plays a part in cellular adhesion and migration making it essential for development and wound healing processes. As a central player in these activities RhoA affects several cellular responses to external stimuli.

Pathways

Research places RhoA prominently in the regulation of the Rho-ROCK (Rho-associated protein kinase) pathway and the planar cell polarity pathway. The Rho-ROCK pathway contributes to cytoskeletal dynamics and cell contractility while the planar cell polarity pathway influences tissue architecture during embryonic development. RhoA interacts with G17A in these pathways coordinating activities such as smooth muscle contraction and neuronal growth. These interactions also involve cross-talk with other signals linked to GTPases like Rac1 and Cdc42.

RhoA has connections to cancer progression and hypertension. In cancer RhoA regulates actin dynamics influencing tumor cell migration and invasion. It forms interactions with proteins such as p53 affecting apoptotic pathways and tumor suppression. In hypertension RhoA's role in smooth muscle contraction affects blood vessel tension and blood pressure regulation. Abnormal activity in the Rho-ROCK pathway contributes to these disorders highlighting the significance of RhoA in disease mechanisms.

Target data

Small GTPase which cycles between an active GTP-bound and an inactive GDP-bound state. Mainly associated with cytoskeleton organization, in active state binds to a variety of effector proteins to regulate cellular responses such as cytoskeletal dynamics, cell migration and cell cycle (PubMed : 23871831). Regulates a signal transduction pathway linking plasma membrane receptors to the assembly of focal adhesions and actin stress fibers (PubMed : 31570889, PubMed : 8910519, PubMed : 9121475). Involved in a microtubule-dependent signal that is required for the myosin contractile ring formation during cell cycle cytokinesis (PubMed : 12900402, PubMed : 16236794). Plays an essential role in cleavage furrow formation. Required for the apical junction formation of keratinocyte cell-cell adhesion (PubMed : 20974804, PubMed : 23940119). Essential for the SPATA13-mediated regulation of cell migration and adhesion assembly and disassembly (PubMed : 19934221). The MEMO1-RHOA-DIAPH1 signaling pathway plays an important role in ERBB2-dependent stabilization of microtubules at the cell cortex. It controls the localization of APC and CLASP2 to the cell membrane, via the regulation of GSK3B activity. In turn, membrane-bound APC allows the localization of the MACF1 to the cell membrane, which is required for microtubule capture and stabilization (PubMed : 20937854). Involved in the reorientation of endothelial cells and their actin stress fibers in response to cellular mechantransduction-mediated activation by ARHGEF40 (By similarity). Regulates KCNA2 potassium channel activity by reducing its location at the cell surface in response to CHRM1 activation; promotes KCNA2 endocytosis (PubMed : 19403695, PubMed : 9635436). Acts as an allosteric activator of guanine nucleotide exchange factor ECT2 by binding in its activated GTP-bound form to the PH domain of ECT2 which stimulates the release of PH inhibition and promotes the binding of substrate RHOA to the ECT2 catalytic center (PubMed : 31888991). May be an activator of PLCE1 (PubMed : 16103226). In neurons, involved in the inhibition of the initial spine growth. Upon activation by CaMKII, modulates dendritic spine structural plasticity by relaying CaMKII transient activation to synapse-specific, long-term signaling (By similarity). Acts as a regulator of platelet alpha-granule release during activation and aggregation of platelets (By similarity). When activated by DAAM1 may signal centrosome maturation and chromosomal segregation during cell division. May also be involved in contractile ring formation during cytokinesis.. (Microbial infection) Serves as a target for the yopT cysteine peptidase from Yersinia pestis, vector of the plague.
