Human Carboxypeptidase A2/CPA2 Antibody Summary

Species Reactivity

Human

Specificity

Detects human Carboxypeptidase A2/CPA2 in direct ELISAs and Western blots. In direct ELISAs and Western blots, no cross-reactivity with recombinant human (rh) CPA1, rhCPA4, rhCPB1, or rhCPE is observed. Recognizes the pro form (aa 17‑417), but not the activated enzyme (aa 113‑417) in Western blots.

Background: Carboxypeptidase A2/CPA2

Carboxypeptidase A2 encoded by the CPA2 gene cleaves the C-terminal amide or ester bond of peptides that have a free C-terminal carboxyl group (1). It prefers the C-terminal residues with aromatic side chains including Phe, Tyr, and Trp. The deduced amino acid sequence of human CPA2 consists of a signal peptide (aa 1 to 16), a pro region (aa 17 to 112), and a mature chain (aa 113 to 417). The amino acid sequence of human CPA2 is 99.5%, 90%, 87%, 86% and 70% identical to that of chimpanzee, canine, rat, mouse and chicken.
