CPB1 (Carboxypeptidase B1) is a Protein Coding gene. Diseases associated with CPB1 include Acute Pancreatitis and Pancreatitis. Among its related pathways are Collagen chain trimerization and Peptide hormone metabolism. Three different procarboxypeptidases A and two different procarboxypeptidases B have been isolated. The B1 and B2 forms differ from each other mainly in isoelectric point. Carboxypeptidase B1 is a highly tissue-specific protein and is a useful serum marker for acute pancreatitis and dysfunction of pancreatic transplants. It is not elevated in pancreatic carcinoma.
