MGI Phenotype FUNCTION: This gene encodes carboxypeptidase E, a prohormone-processing exopeptidase found in secretory granules of endocrine and neuroendocrine cells. The encoded preproprotein undergoes proteolytic processing to generate a mature, functional enzyme that cleaves the C-terminal basic residues of protein substrates. A missense mutation in this gene is responsible for the obesity phenotype in a mouse model known as the "fat mouse." Mice lacking the functional product of this gene exhibit impaired processing of multiple peptide hormones such as proinsulin, prodynorphin, proneurotensin, promelanin-concentrating hormone and pro-opiomelanocortin.

PHENOTYPE: Mice homozygous for a spontaneous or a targeted null mutation display progressive obesity, abnormal blood glucose and lipid regulation, and have reduced fertility. Aberrant prohormone processing and secretion appears to be the cause of these phenotypes. [provided by MGI curators]
