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