Muscle protein that makes vertebrates more fit linked to limited lifespan

Researchers say they have added to evidence that a protein called CaMKII improves strength, endurance, muscle health and fitness in young animals. Their experiments working with mice and fruit flies, however, found that the gene for CaMKII also contributes to an evolutionary tradeoff: increased susceptibility to age-associated diseases, frailty and mortality.
