Carboxypeptidase N Is Not Protein in the Mouse, Whereas Pro-carboxypeptidase R Is an Acute Phase

The pro region is not required for the expression or intracellular routeing of carboxypeptidase E.

Carboxypeptidase E (CPE) is initially synthesized as a larger precursor containing an additional 14-residue propeptide that is highly conserved between human and rat. Previous studies have established that the proenzyme is enzymically active and that deletion of the pro region does not affect the expression of the active enzyme. In the present study the function of the pro region was examined b...

Carboxypeptidase E in the mouse placenta.

Carboxypeptidase E (CPE) has important functions in processing of endocrine pro-peptides, such as pro-insulin, pro-opiomelanocortin, or pro-gonadotropin-releasing hormone, as evidenced by the hyper-pro-insulinemia, obesity, and sterility of Cpe mutant mice. Down-regulation of Cpe in enlarged placentas of interspecific hybrid (interspecies hybrid placental dysplasia (IHPD)) and cloned mice sugge...

Carboxypeptidase D is an avian hepatitis B virus receptor.

The receptor molecules for human and animal hepatitis B viruses have not been defined. Previous studies have described a 170 to 180 kDa molecule (p170 or gp180) that binds in vitro to the pre-S domain of the large envelope protein of duck hepatitis B virus (DHBV); cDNA cloning revealed the binding protein to be duck carboxypeptidase D (DCPD). In the present study, the DCPD cDNA was transfected ...
