Predicted to enable actin filament binding activity; identical protein binding activity; and transmembrane transporter binding activity. Predicted to be involved in several processes, including positive regulation of skeletal muscle tissue development; regulation of generation of precursor metabolites and energy; and regulation of muscle system process. Predicted to act upstream of or within muscle contraction. Predicted to be located in brush border; focal adhesion; and sarcomere. Predicted to be active in several cellular components, including Z disc; cell junction; and cortical actin cytoskeleton. Orthologous to human ACTN3 (actinin alpha 3).
