Automated description from the Alliance of Genome Resources (Release 5.2.2)
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 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).
