Signal Transduction by Cxc Chemokine Receptor 4

Signal Transduction by Cxc Chemokine Receptor 4

We report that stromal cell-derived factor (SDF)-1 has the remarkable capacity to induce sustained signaling through CXC chemokine receptor 4 (CXCR4). In contrast to other chemokines, such as monocyte chemotactic protein 1 (CC chemokine receptor 2 [CCR2]), macrophage inflammatory protein 1beta (CCR5), liver and activation-regulated chemokine (LARC [CCR6]), Epstein-Barr virus-induced molecule 1 ...

Signal transmission through the CXC chemokine receptor 4 (CXCR4) transmembrane helices.

The atomic-level mechanisms by which G protein-coupled receptors (GPCRs) transmit extracellular ligand binding events through their transmembrane helices to activate intracellular G proteins remain unclear. Using a comprehensive library of mutations covering all 352 residues of the GPCR CXC chemokine receptor 4 (CXCR4), we identified 41 amino acids that are required for signaling induced by the...

An analysis of the human chemokine CXC receptor 4 gene.

In this article we analyze some of the structural characteristics of the coding section and the intron of the human chemokine CXC receptor 4 (a 7-transmembrane receptor) pre-mRNA. In the coding sequence the frequencies of the individual nucleotides do not depart significantly from 0.25, while in the intron the frequencies of the As and Gs are significantly lower and higher, respectively, than e...

CXC motif chemokine receptor 4 gene polymorphism and cancer risk

BACKGROUND Previous epidemiological studies have reported the relationship between CXC motif chemokine receptor 4 (CXCR4) synonymous polymorphism (rs2228014), and risk of cancer, but the results remained conflicting and controversial. Therefore, this study was devised to evaluate the genetic effects of the rs2228014 polymorphism on cancer risk in a large meta-analysis. METHODS The computer-ba...
