Pak2 Gene Summary [Mouse]

Enables protein serine/threonine kinase activity. Acts upstream of or within dendritic spine development. Is active in glutamatergic synapse and postsynaptic density. Is expressed in several structures, including nervous system. Used to study autism spectrum disorder. Human ortholog(s) of this gene implicated in ductal carcinoma in situ. Orthologous to human PAK2 (p21 (RAC1) activated kinase 2). [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 Pak2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
