Limited and defined truncation at the C terminus enhances receptor binding and degranulation activity of the neutrophil-activating peptide 2 (NAP-2). Comparison of native and recombinant NAP-2 variants.

Abstract excerpt

We have previously described a C-terminally truncated variant of the chemokine neutrophil-activating peptide 2 (NAP-2) that exhibited higher neutrophil-stimulating capacity than the full-size polypeptide. To investigate the impact of the NAP-2 C terminus on biological activity and receptor binding, we have now purified the novel molecule to homogeneity. Furthermore, we have cloned, expressed in Escherichia coli,...
