Electrophoretic and immunological study of myosin light chains from freshwater teleost fishes.
White muscle myosin light chains from nine freshwater teleosts show a qualitative and quantitative variability on PAGE without phylogenetic correlation. They look different from their higher vertebrate counterparts mainly with regard to electric charge and relative amounts of alkali light chains corresponding to various contents of isoenzymic forms of white muscle myosin. Antibodies against carp white myosin LC1 recognize almost entirely white muscle LC1 from the other fishes and to a lesser degree LC1 from other muscles and vertebrates. The primary structure of this light chain is thus relatively constant. LC2 from carp cardiac muscle and mammalian slow and cardiac muscle do not react at all.
