Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in B cell homeostasis; dendritic spine morphogenesis; and marginal zone B cell differentiation. Located in dendritic spine. Is active in glutamatergic synapse and postsynapse. Is expressed in several structures, including central nervous system; endocrine gland; retina; thymus primordium; and trigeminal nerve. Orthologous to human DOCK10 (dedicator of cytokinesis 10).
