GENE INFORMATION
Gene name	CPB1
Synonyms
Description	Carboxypeptidase B1 (tissue) (HGNC Symbol)
Entrez gene summary	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.
