WebbSmooth 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.
