Last Modified 2014-10-13 [Report errors or provide feedback]
Gene Symbol Cpe
Protein Name carboxypeptidase E
Synonyms CPH; Cph-1; Cph1; fat; R74677;
Species Mus musculus
Ensembl Protein ENSMUSP00000048555
InnateDB Gene IDBG-158252 (Cpe)
Protein Structure
UniProt Annotation
Function Removes residual C-terminal Arg or Lys remaining after initial endoprotease cleavage during prohormone processing. Processes proinsulin.
Subcellular Localization Cytoplasmic vesicle, secretory vesicle membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}. Secreted {ECO:0000250}. Note=Associated with the secretory granule membrane through direct binding to lipid rafts in intragranular conditions. This binding is Ca(2+)-dependent (By similarity). {ECO:0000250}.
Disease Associations Note=Defects in Cpe are the cause of the fat phenotype. Mice homozygous for the fat mutation develop obesity and hyperglycemia that can be suppressed by treatment with exogenous insulin.
