Predicted to enable ATP binding activity. Involved in skeletal muscle fiber development. Predicted to be located in actin cytoskeleton and sarcomere. Predicted to be part of dynactin complex. Predicted to be active in actin filament; stress fiber; and striated muscle thin filament. Is expressed in several structures, including alimentary system; brain; genitourinary system; heart; and limb. Used to study nemaline myopathy 3. Human ortholog(s) of this gene implicated in congenital fiber-type disproportion and nemaline myopathy 3. Orthologous to human ACTA1 (actin alpha 1, skeletal muscle).
