Enables several functions, including D2 dopamine receptor binding activity; enzyme binding activity; and protein domain specific binding activity. Involved in several processes, including positive regulation of transport; regulation of plasma membrane bounded cell projection assembly; and regulation of signal transduction. Located in several cellular components, including Golgi apparatus; cytoplasmic vesicle; and ruffle membrane. Part of protein-containing complex. Is active in glutamatergic synapse and postsynaptic density, intracellular component. Colocalizes with growth cone. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease dominant intermediate B; centronuclear myopathy 1; and lethal congenital contracture syndrome. Orthologous to human DNM2 (dynamin 2). [provided by Alliance of Genome Resources, Apr 2022]
