Predicted to enable several functions, including G protein-coupled glutamate receptor binding activity; GTPase activity; and nitric-oxide synthase binding activity. Predicted to be a structural constituent of postsynapse. Involved in synaptic vesicle budding from presynaptic endocytic zone membrane. Located in photoreceptor inner segment and presynapse. Is expressed in several structures, including 1st branchial arch; central nervous system; genitourinary system; musculature; and paraxial mesenchyme. Orthologous to human DNM3 (dynamin 3).
