NEUTROPHIL-ACTIVATING PEPTIDE-2

摘要

Peptides having the amino acid sequence <IMAGE> AGE> <IMAGE> wherein X is H, Asp-Leu-Tyr-, Ser-Asp-Leu-Tyr- or Asp-Ser-Asp-Leu-Tyr-. The peptide wherein X is H is human neutrophil-activating peptide-2 (hNAP-2) and those wherein X is other than H are natural variants thereof. The peptides have neutrophil-stimulating activity, are structurally related to NAF/NAP-1, beta -thromboglobulin, PBP and CTAP-III and may be isolated from leukocytes and platelets and synthesized by standard peptide synthesis processes and recombinant DNA techniques.
