Predicted to be a structural constituent of postsynaptic actin cytoskeleton. Predicted to be located in several cellular components, including actin cytoskeleton; dense body; and focal adhesion. Predicted to be active in actin filament. Is expressed in several structures, including eye; hematopoietic cell; liver; male organism; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in Baraitser-Winter syndrome and autosomal dominant nonsyndromic deafness 20. Orthologous to several human genes including ACTB (actin beta).
