Predicted to enable actin binding activity. Predicted to be involved in cytoskeleton organization; modification of postsynaptic actin cytoskeleton; and regulation of cell shape. Predicted to act upstream of or within lamellipodium assembly; oligodendrocyte development; and positive regulation of myelination. Predicted to be located in lamellipodium. Predicted to be active in glutamatergic synapse and postsynapse. Orthologous to human WASF3 (WASP family member 3). [provided by Alliance of Genome Resources, Apr 2022]
