Scope note

  • A diverse superfamily of proteins that function as translocating proteins. They share the common characteristics of being able to bind ACTINS and hydrolyze MgATP. Myosins generally consist of heavy chains which are involved in locomotion, and light chains which are involved in regulation. Within the structure of myosin heavy chain are three domains: the head, the neck and the tail. The head region of the heavy chain contains the actin binding domain and MgATPase domain which provides energy for locomotion. The neck region is involved in binding the light-chains. The tail region provides the anchoring point that maintains the position of the heavy chain. The superfamily of myosins is organized into structural classes based upon the type and arrangement of the subunits they contain.

History note

  • 2002(1971); use ADENOSINE TRIPHOSPHATASE 1963-1968; for MYOSIN ATPASE use ADENOSINETRIPHOSPHATASE 1984-1988; for ACTOMYOSIN ATPASE use ADENOSINETRIPHOSPHATASE 1985-1988
