While the vast majority of these enzymes appear to be membrane-bound, some family members have been identified as soluble secreted proteins (Turner et al., 2001). In humans, seven members of the M13 family are known, namely Neprilysin (NEP), endothelin-converting enzymes (ECE1, ECE2), ECEL1, MMEL1, the KELL blood-group protein and PHEX (Turner and Tanzawa 1997). Among these, NEP is characterized best, with identified substrates including endothelins, angiotensins I and II, enkephalins, bradykinin, atrial natriuretic peptide, substance P and the amyloid-beta peptide (Turner et al., 2001, Nalivaeva et al., 2020). NEP-mediated hydrolysis is critical to maintain the physiological homeostasis of these peptides, and thus represents a prerequisite for proper endocrine signal transmission. Accordingly, impaired neprilysin activity in humans is involved in the pathogenesis of numerous diseases, including hypertension (Molinaro et al., 2002), analgesia (Whitworth 2003), cancer (Turner et al., 2001) and Alzheimer’s disease (Iwata et al., 2000, Belyaev et al., 2009). Clinical trials have confirmed the therapeutic potential of modulating neprilysin activity (Jessup 2014). PY - 2021 JO - microPublication Biology ER -
