Acta1 Gene Summary [Mouse]

Predicted to enable ATP binding activity and hydrolase activity. Involved in skeletal muscle fiber development. Predicted to be located in several cellular components, including filopodium; lamellipodium; and sarcomere. Predicted to be part of protein-containing 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 myopathy 2B; congenital myopathy 2C; and nemaline myopathy 3. Orthologous to human ACTA1 (actin alpha 1, skeletal muscle).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Acta1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
