Figure 1. Skeletal muscle eEF2 kinase activity is Ca²⁺–calmodulin dependent.

eEF2 kinase was immunoprecipitated from human skeletal muscle samples and activity was measured in vitro in the absence and presence of Ca²⁺–calmodulin (Ca²⁺-CaM). Data are mean ±s.e.m. from 4 samples, *P < 0.01 versus EGTA.
