Summary of Carboxypeptidase E (CPE) Activities Regulating Bone Mass and Energy Balance

CPE activities Metabolic and skeletal functions
Enzymatic carboxypeptidase activity Energy balance, negative regulation of obesity and bone marrow adipocyte tissue accumulation
Endogenous nonenzymatic activity Negative regulation of osteoclast differentiation
Trophic nonenzymatic activity Regulation of osteoblast bioenergetics and ERK1/2 signaling
