Predicted Molecular Mass:8.0 kDa Activity:Measured by its ability to induce myeloperoxidase release from cytochalasin B-treated human neutrophils. Schröder, J.M. etal. (1987) J.Immunol. 139:3474.The ED₅₀ for this effect is typically 0.5-1.5µg/mL.Measured by its ability to chemoattract BaF3 mouse pro‑B cells transfected with human CXCR2.The ED₅₀ for this effect is typically 0.3 - 1.5 ng/mL. Molecule Information: CXCL5/ENA-74 Aliases: ENA-74 Entrez Gene IDs: 6374 (Human) Background: CXCL5/ENA Epithelial cell-derived neutrophil-activating peptide 78 (ENA-78) is a member of the CXC subfamily of chemokines. ENA-78 cDNA encodes a 114 amino acid (aa) precursor protein with a putative 36 aa signal peptide that is cleaved to produce the 78 aa mature protein containing a stretch of 12 aa preceding the CXC motif. Proteolysis of ENA-78 with Cathepsin G and chymotrypsin have yielded N terminally truncated variants with increased biological activities, ENA-70 and ENA-74.
