Myo18a Gene Summary [Mouse]
Predicted to enable ADP binding activity; ATP binding activity; and actin filament binding activity. Involved in positive regulation of opsonization and regulation of macrophage activation. Acts upstream of or within cellular response to type II interferon. Located in brush border; cytoskeleton; and phagocytic vesicle. Is expressed in several structures, including gonad; lower leg rest of mesenchyme; molar; musculature; and nervous system. Orthologous to human MYO18A (myosin XVIIIA).

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 Myo18a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
