Biochem/physiol Actions
Nonmuscle myosin II is involved in cell motility and adhesion, cytokinesis, vesicular transport, intracellular force generation and in morphogenesis during development. Its activity is regulated by light chain and possibly heavy chain phosphorylation and by association with proteins such as Mts1. Mutations in the NMHCA gene are found in several syndromes associated with megakaryocyte/platelet/leukocyte disorders. Mutations in the MYH9 gene causes a spectrum of macrothrombocytopenia disorders with neutrophil inclusions, termed as MYH9 disorders.
