[[http://www.uniprot.org/uniprot/MYS_ARGIR MYS_ARGIR]] Muscle contraction.  Myosin is a protein that binds to F-actin and has ATPase activity that is activated by F-actin. [[http://www.uniprot.org/uniprot/MLE_ARGIR MLE_ARGIR]] 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.
