Rac1 Gene Summary [Rat]
Enables several functions, including GTP binding activity; Rho GDP-dissociation inhibitor binding activity; and enzyme binding activity. Involved in several processes, including actin cytoskeleton organization; bone resorption; and positive regulation of plasma membrane bounded cell projection assembly. Located in Golgi membrane and cytosol. Is active in GABA-ergic synapse. Used to study congestive heart failure. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 48; colorectal cancer (multiple); lung cancer; and pancreatic adenocarcinoma. Orthologous to human RAC1 (Rac family small GTPase 1). [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 rat Rac1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
