WebSmooth muscle myosin heavy chains (SMHCs) are motor proteins that power smooth muscle contraction. SMHCs have two main isoforms: SM1 and SM2. SM1 is expressed in SMCs throughout embryonic development to the mature stage, whereas SM2 has a distinct function for smooth muscle contraction and is a specific marker of mature SMCs. WebThere is a smooth muscle-specific myosin heavy chain gene and the genes for the light chains of smooth muscle myosin differ from those of skeletal muscles. In place of well-defined Z-lines, smooth muscles have dense bodies which contain a smooth muscle-specific isoform of α -actinin.
