Arhgef18

Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in negative regulation of stress fiber assembly; protein localization to cell-cell junction; and regulation of Rho protein signal transduction. Predicted to act upstream of or within actin cytoskeleton organization; regulation of cell shape; and small GTPase-mediated signal transduction. Predicted to be located in apical part of cell and cytosol. Predicted to be active in plasma membrane. Is expressed in brain; genitourinary system; integument; and liver. Human ortholog(s) of this gene implicated in retinitis pigmentosa. Orthologous to human ARHGEF18 (Rho/Rac guanine nucleotide exchange factor 18). [provided by Alliance of Genome Resources, Apr 2025]

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Arhgef18 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
