Myosin regulatory light chain, striated adductor muscle

UniProtKB accession:  P13543

Grouped By:  Matching UniProtKB accession

UniProtKB description:  In molluscan muscle, calcium regulation is associated with myosin rather than with actin. Muscle myosin contains two types of light chains: the catalytic light chain, essential for ATPase activity, and the regulatory light chain, a calcium-binding protein responsible for Ca(2+) dependent binding and Ca(2+) dependent Mg-ATPase activity.
