OverviewNCBI Gene

Myosin is a major contractile protein which converts chemical energy into mechanical energy through the hydrolysis of ATP. Myosin is a hexameric protein composed of a pair of myosin heavy chains (MYH) and two pairs of nonidentical light chains. Myosin heavy chains are encoded by a multigene family. In mammals at least 10 different myosin heavy chain (MYH) isoforms have been described from striated, smooth, and nonmuscle cells. These isoforms show expression that is spatially and temporally regulated during development. [provided by RefSeq, Jul 2008]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads MYH1 as an antibody target. Whether an autoantibody or antibody against MYH1 could matter depends on whether native MYH1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

MYH1 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label MYH1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
