Anti-CXCR4

0.5mg/ml if reconstituted with 0.2ml sterile DI water. Chemokine,CXC Motif, Receptor 4, also known as FUSIN or NPY3R, is a protein that in humans is encoded by the CXCR4 gene. By PCR analysis of human/hamster hybrid cell DNA, Herzog et al.(1993) showed that the NPY3R gene is located on human chromosome 2. Feng et al.(1996) showed that transient expression of the gene allowed nonhuman cells coexpressing recombinant CD4 to undergo Env-CD4-mediated cell fusion and productive HIV-1 infection. Peled et al.(1999) demonstrated that SDF1 and its receptor CXCR4 are critical for murine bone marrow engraftment by human SCID repopulating stem cells. Treatment of human cells with anti-CXCR antibodies prevented engraftment. Protein function: Receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces a signal by increasing intracellular calcium ion levels and enhancing MAPK1/MAPK3 activation. Acts as a receptor for extracellular ubiquitin, leading to enhanced intracellular calcium ions and reduced cellular cAMP levels. Involved in hematopoiesis and in cardiac ventricular septum formation. Also plays an essential role in vascularization of the gastrointestinal tract, probably by regulating vascular branching and/or remodeling processes in endothelial cells. Involved in cerebellar development. In the CNS, could mediate hippocampal-neuron survival. [The UniProt Consortium]
