Predicted to enable ATP binding activity and hydrolase activity. Predicted to act upstream of or within mesenchyme migration and positive regulation of gene expression. Predicted to be located in several cellular components, including cell body; filopodium; and lamellipodium. Is expressed in cardiovascular system; mesoderm; musculoskeletal system; and nervous system. Human ortholog(s) of this gene implicated in Moyamoya disease and thoracic aortic aneurysm. Orthologous to human ACTA2 (actin alpha 2, smooth muscle).
