Trends in endocrinology and metabolism: TEM 2022 JunProteolysis of protein hormones is primarily acknowledged in the context of breakdown and metabolic clearance by hepatorenal elimination. However, less explored is the specific proteolytic processing of large protein hormones, for which canonical signaling pathways were already established [e.g., prolactin (PRL)], to generate unique messengers that impact cellular functions via pathways unrelated to the receptors of their precursor molecules. Yet, the proteolysis of PRL to generate new messengers evolved under positive selection, and cleaved protein hormones regulate essential functions to maintain homeostasis at the organismal, tissue, or organ levels. The cleavage sites at which proteolysis occurs and the proteases with their determinants define a hormone-metabolism junction at which specific proteolytic cleavage, pathological alteration, and hepatorenal elimination occur.
