Members of the chemokine family of chemotactic peptides interact with their target cells through heptahelical cell surface receptors. An understanding of the biochemistry and expression patterns of these receptors is therefore central to our overall understanding of the roles played by chemokines in both physiological and pathological processes. To date, eight receptors for the beta-chemokine subfamily have been described. We have recently cloned a novel murine beta-chemokine receptor and report here the identification and characterization of a highly homologous human gene termed human D6 (hD6). This is a promiscuous beta-chemokine receptor and appears to be able to bind the majority of members of the beta-chemokine family. It is, however, specific for this family and shows no detectable affinity for members of the alpha-chemokine or the C or CXXXC chemokines. Unlike the majority of other chemokine receptors, human D6 does not appear to be able to flux calcium following ligand binding, thus it is currently not clear if this novel receptor is indeed a signaling receptor. Human D6 is expressed in a range of tissues including hemopoietic cells although it appears not to be ubiquitously expressed in hemopoietic cells. Human D6, unlike some other beta-chemokine receptors, appears not to be able to function as an entry co-factor for human immunodeficiency virus type 1 (HIV-)1 on CD4-expressing cells.

UI MeSH Term Description Entries
D008024 Ligands A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed) Ligand
D008969 Molecular Sequence Data Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories. Sequence Data, Molecular,Molecular Sequencing Data,Data, Molecular Sequence,Data, Molecular Sequencing,Sequencing Data, Molecular
D011485 Protein Binding The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments. Plasma Protein Binding Capacity,Binding, Protein
D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.
