Dock2 Gene Summary [Mouse]
Enables GTPase activator activity. Involved in macropinocytosis; myeloid dendritic cell activation involved in immune response; and positive regulation of phagocytosis. Acts upstream of or within several processes, including T cell activation; immunological synapse formation; and membrane raft polarization. Predicted to be located in cytoskeleton; endomembrane system; and membrane. Predicted to be active in cytoplasm and plasma membrane. Is expressed in central nervous system; paraxial mesenchyme; and retina. Human ortholog(s) of this gene implicated in immunodeficiency 40. Orthologous to human DOCK2 (dedicator of cytokinesis 2).

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 Dock2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
