The results reported in this dissertation provide evidence that the cysteine protease, cathepsin B, is one of the nonmuscle-specific genes expressed in a regulated manner during myogenesis. Unlike muscle-specific enzymes such as creatine phosphokinase (CPK), levels of cathepsin B activity are high in dividing, presumptive myoblasts. As these cells align in linear arrays in preparation for fusion, levels of cathepsin B activity drop dramatically and then increase in a fusion-related manner characteristic of muscle specific enzymes. This current studies appears to be the first to demonstrate a "down-up" pattern of cathepsin B activity over the entire differentiation process in vitro and to provide both indirect and direct evidence for the role of cathepsin B in myogenesis.
