Rac3 Gene Summary [Mouse]
Predicted to enable several functions, including GTP binding activity; GTPase activity; and calcium-dependent protein binding activity. Involved in regulation of postsynapse assembly. Acts upstream of or within several processes, including GABAergic synaptic transmission; neuron development; and regulation of neuron maturation. Is active in glutamatergic synapse and postsynapse. Is expressed in brain and genitourinary system. Orthologous to human RAC3 (Rac family small GTPase 3). [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 Rac3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
