Probable serine carboxypeptidase CPVL is an enzyme that in humans is encoded by the CPVL gene. The "CPVL" gene is expressed mainly in monocytes and macrophages, and it is located in the endoplasmatic reticulum and in the endosomal/lysosomal compartment. The distribution of CPVL suggests that the enzyme may be involved in antigen processing and the secretory pathway. Besides those macrophages-rich tissues, the heart and kidney also express high levels of CPVL mRNA.The enzyme is similar to the carboxypeptidases CATHA and SCPEP1, but no direct confirmation of the enzymatic activity was obtained so far. The exact function of this protein, however, has not been determined.
