Predicted to enable ATP binding activity. Involved in several processes, including response to lithium ion; response to steroid hormone; and skeletal muscle fiber adaptation. Predicted to be located in several cellular components, including filopodium; lamellipodium; and sarcomere. Predicted to be part of dynactin complex. Predicted to be active in actin filament; stress fiber; and striated muscle thin filament. 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). [provided by Alliance of Genome Resources, Apr 2022]
