Comparison of the primary structure of CHEMR1 with other chemokine receptors. Shown is an alignment of CHEMR1 with CCR-4, the MIP-1α/RANTES receptor (CCR-1), eosinophil-derived C-C chemokine receptor (CCR-3), the MCP-1 receptor (CCR-2A), the two IL-8 receptors, and fusin (HUMSTSR), the T-tropic HIV-1 cofactor. The conserved residues are indicated in a box. A potential G-protein binding domain is indicated by asterisks.45 (○) A putative disulfide bridge that forms a ligand binding domain.45 (▪) A potential N-glycosylation site.
