Protein Structure

UniProt Annotation

Function

Carboxypeptidase that may play an important role in the hydrolysis of circulating peptides. Catalyzes the hydrolysis of dipeptides with unsubstituted terminals into amino acids. May play a role in the liberation of thyroxine hormone from its thyroglobulin (Tg) precursor (By similarity). {ECO:0000250}.

Subcellular Localization

Endoplasmic reticulum {ECO:0000250}. Golgi apparatus {ECO:0000250}. Lysosome {ECO:0000250}. Secreted {ECO:0000250}. Note=Secretion is stimulated by TSH/thyroid- stimulating hormone, INS/insulin and SST/somatostatin. {ECO:0000250}.
