Predicted to enable actin filament binding activity. Involved in several processes, including embryonic body morphogenesis; nematode larval development; and regulation of growth. Predicted to be located in several cellular components, including cell junction; cortical actin cytoskeleton; and plasma membrane. Expressed in several structures, including body wall musculature; hermaphrodite gonad; intestine; pharynx; and vulval cell. Human ortholog(s) of this gene implicated in autosomal dominant distal hereditary motor neuronopathy 11; developmental and epileptic encephalopathy 5; and hereditary spherocytosis type 3. Is an ortholog of human SPTAN1 (spectrin alpha, non-erythrocytic 1).
