|Description||Rat NAP-2/CXCL7 is a small cytokine belonging to the CXC chemokine family. It is an isoform of Beta-Thromboglobulin or Pro-Platelet basic protein (PPBP). Similar to other ELR domain containing CXC chemokines such as IL-8 and the GRO proteins, NAP-2 has been shown to bind CXCR-2 and recruit and active ateneutrophils through chemotaxis. Although CTAP-III, β-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. NAP-2 stimulates various processes including mitogenesis, synthesis of the extracellular matrix, glucose metabolism and synthesis of plasminogen activator. Recently, it has been shown that the additional amino-terminal residues of CTAP-III mask the critical ELR receptor binding domain that is exposed on NAP-2 and may account for lack of NAP-2 activity.
Recombinant Rat NAP-2 /CXCL7 produced in E.coli is a single non-glycosylated polypeptide chain containing 62 amino acids. A fully biologically active molecule, rrNAP-2/CXCL7 has a molecular mass of 6.9 kD analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
