Web1 aug. 1997 · The class I myosins are single-headed, actin-binding, mechanochemical “motor” proteins with heavy chains in the molecular mass range of 110-130 kDa; they do not form filaments. Each myosin I heavy chain is associated with one to six light chains that bind to specific motifs known as IQ domains.
