Supplementary information

Rho proteins including Rho A B and C are small GTPases and part of the larger Rho family sometimes referred as Ras homologous proteins. They have a mass of approximately 21 kDa and play an important role in actin cytoskeleton dynamics. These proteins are primarily expressed in various tissues but are especially prevalent in the brain heart and lungs. When activated Rho proteins bind to GTP facilitating the reorganization of actin fibers critical for processes like cell movement and division.
Biological function summary

Rho proteins influence cell shape migration and adhesion. They are part of the Rho GTPase family which interacts with other molecules to form a complex that manages cellular structure. Rho proteins impact the formation of stress fibers and focal adhesions which are essential for maintaining tissue integrity and facilitating cellular responses. This activity makes Rho proteins vital players in wound healing and embryonic development.

Pathways

Rho proteins are critical parts of the Rho-ROCK (Rho-associated protein kinase) pathway and the Wnt signaling pathway. Both pathways are important for cell signaling that orchestrates changes in the cytoskeleton and cell behavior. In these pathways Rho proteins interact with kinases like ROCK1 and ROCK2 connecting to a larger network of signaling proteins that guide cellular outcomes involved in proliferation and structural maintenance.

Rho proteins have connections to cancer progression and cardiovascular diseases. Their role in cell adhesion and migration links them to metastasis where their dysregulation can promote tumor invasion. Also in cardiovascular conditions altered Rho activity impacts vascular smooth muscle contraction and endothelial function. Research associations identify proteins like E-cadherin in cancer and vascular endothelial cadherin in heart diseases as being influenced by Rho protein signaling.

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). 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.
