Recombinant Human CXCL7/NAP-2 Protein Summary

Details of Functionality
Measured by its ability to induce myeloperoxidase release from cytochalasin B-treated human neutrophils. Schröder, J.M. et al. (1987) J. Immunol. 139:3474. The ED50 for this effect is 0.1‑0.3 μg/mL. Measured by its ability to chemoattract BaF3 mouse pro‑B cells transfected with human CXCR2. The ED50 for this effect is 0.1‑0.5 ng/mL.

Neutrophil Activating Peptide 2 (NAP-2), Connective Tissue Activating Protein III (CTAP-III) and beta -thrombogulin ( beta -TG), are proteolytically processed carboxyl-terminal fragments of platelet basic protein (PBP) which is found in the alpha-granules of human platelets. NAP-2 is a member of the CXC chemokines. Similar to other ELR domain containing CXC chemokines such as IL-8 and the GRO proteins, NAP-2 has been shown to bind CXCR2 and to chemoattract and activate neutrophils. Although CTAP-III, beta -TG and PBP represent amino-terminal extended variants of NAP-2 and possess the same CXC chemokine domains, these proteins do not exhibit NAP-2 activity. It has been shown that the additional amino-terminal residues of CTAP-III masks the critical ELR receptor binding domain that is exposed on NAP-2 and may account for lack of NAP-2 activity.
