Myh4 Gene Summary [Rat]
Predicted to enable actin filament binding activity; double-stranded RNA binding activity; and microfilament motor activity. Involved in several processes, including response to gravity; response to muscle activity; and response to muscle stretch. Predicted to be located in myofibril. Predicted to be part of myosin II complex. Predicted to be active in cytoplasm and myosin filament. Biomarker of sciatic neuropathy. Orthologous to human MYH4 (myosin heavy chain 4).

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 Myh4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
