Isoform patterns distinguish Xenopus fiber types by contractility; leaves open extension to mammalian cardiac myosin function.
The study demonstrates that amphibian skeletal muscle possesses distinct myosin isoenzyme profiles corresponding to five functional fibre types, suggesting similarities with mammalian and avian muscle.
Lännergren et al. (1984) studied Isolated skeletal muscle fibres from Xenopus laevis. Myosin isoenzyme composition analysis was evaluated on Myosin isoenzyme composition across five functional types of muscle fibers. Analysis of isolated skeletal muscle fibers from Xenopus laevis revealed distinct myosin isoenzyme compositions across five functional fiber types, suggesting similarities to mammalian and avian fibers.
