Identifying the mechanisms that regulate post-mortem proteolysis in skeletal muscle is of economic and
environmental importance because it is a crucial process during meat conversion and tenderization. Among the
catabolic systems discussed, the calpain proteolytic system has received much attention. In addition, the muscle of
cattle with double musculature, bearing natural deletions or mutations in the Myostatin gene, is more tender
providing an interesting agro-ecologic way to answer both to reduction of livestock and enhanced quality. In this
context, the study of the contribution of the calpain proteolytic system during post-mortem proteolysis, using the
model of myostatin knock-out mice, brings new answers and poses current reflections, as discussed in this article... View More»
