Subunit composition of native myosin isoenzymes of some striated mammalian muscles.
Six "native" isomyosins of characteristic electrophoretic mobility are present in various proportions according to the muscle type (fast, slow or mixed). SM2 and SM1 contain MHC1; IM contains MHC2A; FM1, FM2 and FM3 contain MHC2A and MHC2B. SM2, SM1 and IM contain MLC1s; SM1, IM, FM2 and FM3 contain MLC1f; FM2 and FM1 contain MLC3f. The six isomyosins appear to separate on the base of their myosin light chain content.
