Myocardin
Myocardin is a protein that in humans is encoded by the MYOCD gene.
Myocardin is a smooth muscle cell and cardiac muscle cell-specific transcriptional coactivator of serum response factor (SRF). When expressed in smooth muscle precursor cells and abnormally in nonmuscle cells, myocardin can induce smooth muscle cell differentiation. Myocardin can also function in the differentiation of myocardial cells.
