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 Arhgap45 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

- protein kinase C conserved region 1 (C1 domain) superfamily
- GTPase activator
- protein binding
- GTPase-activator protein for Rho-like GTPases
