Rap2b Gene Summary [Mouse]

Enables protein domain specific binding activity. Involved in Rap protein signal transduction and regulation of protein tyrosine kinase activity. Acts upstream of or within negative regulation of cell migration and positive regulation of protein autophosphorylation. Located in cytosol and recycling endosome membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and integumental system. Orthologous to human RAP2B (RAP2B, member of RAS oncogene family). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

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 Rap2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
