Functioni

Regulates a signal transduction pathway linking plasma membrane receptors to the assembly of focal adhesions and actin stress fibers. Involved in a microtubule-dependent signal that is required for the myosin contractile ring formation during cell cycle cytokinesis. Plays an essential role in cleavage furrow formation. Required for the apical junction formation of keratinocyte cell-cell adhesion. May be an activator of PLCE1. Activated by ARHGEF2, which promotes the exchange of GDP for GTP. Essential for the SPATA13-mediated regulation of cell migration and adhesion assembly and disassembly. 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 (By similarity). Regulates KCNA2 potassium channel activity by reducing its location at the cell surface in response to CHRM1 activation; promotes KCNA2 endocytosis (By similarity).By similarity

Interacts (in the constitutively activated, GTP-bound form) with DGKQ. Interacts with 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 (By similarity). Interacts with ARHGDIA; this interaction inactivates and stabilizes RHOA. Interacts with ARHGDIB (By similarity). Interacts (GTP-bound form) with KCNA2 (via cytoplasmic N-terminal domain) (By similarity). Interacts (via GTP-bound form) with RIPOR1 (via N-terminus); this interaction links RHOA to STK24 and STK26 kinases (By similarity). Interacts with RIPOR2 (via active GTP- or inactive GDP-bound forms); this interaction is direct, blocks the loading of GTP to RHOA and decreases upon chemokine CCL19 stimulation in primary T lymphocytes (By similarity).By similarity
