Myosin heavy chain type A is a critical component of the cellular contractile apparatus. It is involved in maintaining cell-cell adhesion in early mammalian embryos and ablation of this protein leads to prenatal lethality. Mutation in the human MYH9 gene lead to MYH9-related hereditary macrothrombocytopenia (HMTC) characterized by a reduced number of blood platelets.
