Potentiation of in vitro concentric work in mouse fast muscle.

Phosphorylation of myosin regulatory light chain (R-LC) is associated with potentiated work and power during twitch afterloaded contractions in mouse extensor digitorum longus muscle [R. W. Grange, C. R. Cory, R. Vandenboom, and M. E. Houston. Am. J. Physiol. 269 (Cell Physiol. 38): C713-C724, 1995]. We now describe the association between R-LC… CONTINUE READING
