CPD (Carboxypeptidase D) is a Protein Coding gene. Diseases associated with CPD include Hepatitis B. Among its related pathways are Clathrin derived vesicle budding and Vesicle-mediated transport. The metallocarboxypeptidase family of enzymes is divided into 2 subfamilies based on sequence similarities. The pancreatic carboxypeptidase-like and the regulatory B-type carboxypeptidase subfamilies. Carboxypeptidase D has been identified as a regulatory B-type carboxypeptidase. CPD is a homolog of duck gp180, a hepatitis B virus-binding protein. Transcript variants utilizing alternative polyadenylation signals exist for CPD.
