Gene Symbol | CPA1 |
Entrez Gene ID | 1357 |
Full Name | carboxypeptidase A1 |
Synonyms | CPA |

Gene Type | protein-coding |
Organism | Homo sapiens(human) |
Genome | |
Summary | This gene encodes a member of the carboxypeptidase A family of zinc metalloproteases. This enzyme is produced in the pancreas and preferentially cleaves C-terminal branched-chain and aromatic amino acids from dietary proteins. This gene and several family members are present in a gene cluster on chromosome 7. Mutations in this gene may be linked to chronic pancreatitis, while elevated protein levels may be associated with pancreatic cancer. [provided by RefSeq, Jan 2015]. |

The following CPA1 gene cDNA ORF clone sequences were retrieved from the NCBI Reference Sequence Database (RefSeq). These sequences represent the protein coding region of the CPA1 cDNA ORF which is encoded by the open reading frame (ORF) sequence. ORF sequences can be delivered in our standard vector, pcDNA3.1+/C-(K)DYK or the vector of your choice as an expression/transfection-ready ORF clone. Not the clone you want?
