Predicted to enable ATP binding activity; microfilament motor activity; and myosin binding activity. Involved in cardiac muscle contraction; response to ethanol; and response to xenobiotic stimulus. Predicted to be located in several cellular components, including I band; filopodium; and lamellipodium. Predicted to be part of dynactin complex. Predicted to be active in actin filament; glutamatergic synapse; and sarcomere. Biomarker of hypertension. Human ortholog(s) of this gene implicated in atrial heart septal defect 5; dilated cardiomyopathy; dilated cardiomyopathy 1R; and hypertrophic cardiomyopathy 11. Orthologous to human ACTC1 (actin alpha cardiac muscle 1). [provided by Alliance of Genome Resources, Apr 2022]
