Background: Carboxypeptidase E (CPE), also known as carboxypeptidase H and enkephalin convertase, is found as both a membrane-bound and a soluble glycoprotein in neuroendocrine tissues and adrenal-gland chromaffin granules. The C-terminus forms an amphiphilic alpha-helix, suggesting that this region is responsible for the membrane-bound form. Evidence suggests the active form of CPE is located in the secretory vesicles. CPE appears to have several functions. It is an exopeptidase that cleaves neuropeptides with C-terminal basic amino acids, producing an active form of the peptide. It has also been proposed that membrane-bound CPE is a sorting receptor for regulated secretory pathway (RSP) proteins in the TGN pituitary Golgi and secretory granule membranes. RSP proteins primarily consist of hormones and neuropeptides. Mice that carry a mutation in the CPE gene Cpe[fat] display endocrine disorders such as obesity, infertility, and hyperproinsulinemia. Furthermore, the same endocrine disorders are observed in Cpe[fat] mice where the CPE gene has been effaced by antisense RNA.
