GTP-binding protein RHO1

UniProtKB accession:  P06780

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Acts as a central regulator in the cell wall integrity signaling pathway, which is regulated by the cell cycle and in response to various types of cell wall stress. Integrates signals from different cell surface sensors, and activates a set of effectors, regulating processes including beta-glucan synthesis at the site of wall remodeling, gene expression related to cell wall biogenesis, organization of the actin cytoskeleton, and protein- and secretory vesicle-targeting to the growth site. Activates the protein kinase C (PKC1) MAP kinase cascade, the beta-1,3-glucan synthase (FKS1), the formin BNI1, the exocyst component SEC3 and the transcription factor SKN7.
