CXCL3, also known as Growth-regulated Oncogene gamma (GRO gamma), Macrophage Inflammatory Protein 2 beta (MIP-2beta), Dendritic Cell Inflammatory Protein 1 (DCIP-1), or Cytokine-induced Neutrophil Attractant 2 (CINC-2), is an 8 kDa pro-inflammatory member of the CXC subfamily of heparin-binding chemokines (1-3). Mature human CXCL3 (aa 35-107) shares 70% and 74% amino acid (aa) sequence identity with mouse and rat CXCL3, respectively. CXCL3 binds and activates CXCR2 to induce chemoattraction of CXCR2-expressing cells including neutrophils and endothelial cells (4, 5). Additional N-terminal processing of mature CXCL3 by the removal of aa 35-38 increases its chemotactic activity by several fold (6). In addition to binding CXCR2, CXCL3 can also bind and be sequestered by the Duffy Antigen Receptor for Chemokines (DARC) decoy receptor (7).
