Background: Glycosaminoglycan (GAG)-chemokine dimer interactions regulate neutrophil trafficking, but the molecular basis underlying their interactions is not well understood. Results:NMRstudies of murine CXCL1 indicate that heparin spans the dimer interface and enhances its structural integrity and stability. Conclusion: Heparin binding modulates multiple structural properties of the chemokine dimer. Significance: This study provides novel structural insights into how chemokine dimers orchestrate neutrophil recruitment.
