Arhgap21 Gene Summary [Rat]
Predicted to enable GTPase activator activity. Predicted to be involved in several processes, including establishment of Golgi localization; maintenance of Golgi location; and organelle transport along microtubule. Predicted to act upstream of or within regulation of endocytosis. Predicted to be located in several cellular components, including Golgi apparatus; actin cytoskeleton; and cell junction. Orthologous to human ARHGAP21 (Rho GTPase activating protein 21). [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 Arhgap21 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
