HEMHC is an alias for the gene, Myosin, heavy chain 3, skeletal muscle, embryonic, in humans. Other names include: Myosin-3; Muscle embryonic myosin heavy chain; Myosin heavy chain 3; Myosin heavy chain, fast skeletal muscle, embryonic; SMHCE; myosin, skeletal, heavy chain, embryonic 1; muscle embryonic myosin heavy chain 3; MYHC-EMB; MYHSE1. The encoded protein has an amino acid length of 1940 and a mass of 223.9 kDa. HEMHC is a member of the TRAFAC class myosin-kinesin ATPase superfamily, Myosin family.
