Myosin-3 is a
protein that in humans is encoded by the MYH3gene.[5][6]
Function
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. This gene is a member of the MYH family and encodes a protein with an IQ domain and a myosin head-like domain. Mutations in this gene have been associated with two congenital contracture (
arthrogryposis) syndromes,[7]Freeman–Sheldon syndrome and Sheldon–Hall syndrome.[6]
