Abstract

Several chemokine receptors have been cloned and shown to belong to a superfamily of seven transmembrane, G protein-coupled receptors. We report here the molecular cloning of TER1, a novel human chemokine receptor-like gene. The amino acid sequence deduced from the TER1 cDNA shows 43, 40, 40, and 39% identity to CCR4, CCR5, CCR1, and CCR2B beta chemokine receptors, respectively. By the use of fluorescent in situ hybridization, we have mapped the TER1 gene to chromosome 3p21, clustered with other chemokine receptor genes. By Northern blot analysis, TER1 mRNA is found to be expressed in the thymus, spleen, and at barely detectable levels in peripheral blood lymphocytes. Moreover, TER1 message in abundant in the NK cell line NK3.3 and in the T cell line MOLT-4. The restricted TER1 expression in cells and tissues of the lymphoid lineage suggests that this receptor may play a role in regulating immune functions.
