Myo18a Gene Summary [Rat]

Predicted to enable ADP binding activity; ATP binding activity; and actin filament binding activity. Predicted to be involved in several processes, including asymmetric Golgi ribbon formation; canonical NF-kappaB signal transduction; and positive regulation of transport. Predicted to act upstream of or within cellular response to type II interferon. Predicted to be located in several cellular components, including actomyosin; brush border; and trans-Golgi network. Predicted to be part of myosin II complex. Predicted to be active in cytoplasm and myosin filament. Orthologous to human MYO18A (myosin XVIIIA). [provided by Alliance of Genome Resources, Jul 2025]

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 rat 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.
