| Outline of Final Research Achievements |
Chemokine receptors (CKRs), which are involved in homeostasis, inflammation, and immune response, constitute a subfamily of the G protein-coupled receptors. Both decoy and viral receptors are the homologs of CKRs, but their functions are different not only from those of the typical CKRs, but also from each other. To identify the changes which have induced the functional differentiation of the CKR homologs during the molecular evolution, we compared the three groups with bioinformatics methods.
From amino acid or nucleotide sequence comparisons and model structure buildings, we found that the several sites, which might be involved in the ligand binding and/or the signal transduction in the CKRs, had changed in each group. The results of our analyses would be expected to the modification of GPCR functions and the drug development.
