Background: CXCR4(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 CXCR4 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.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a CXC chemokine receptor specific for stromal cell-derived factor-1. The protein has 7 transmembrane regions and is located on the cell surface. It acts with the CD4 protein to support HIV entry into cells and is also highly expressed in breast cancer cells. Mutations in this gene have been associated with WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
Uniprot Description
CXCR4: 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. Acts as a coreceptor (CD4 being the primary receptor) for HIV-1 X4 isolates and as a primary receptor for some HIV-2 isolates. Promotes Env-mediated fusion of the virus. Monomer. Can form dimers. Interacts with CD164. Interacts with HIV-1 surface protein gp120 and Tat. Interacts with ARRB2; the interaction is dependent on the C-terminal phosphorylation of CXCR4 and allows activation of MAPK1 and MAPK3. Interacts with ARRC; the interaction is dependent on the C-terminal phosphorylation of CXCR4 and modulates calcium mobilization. Interacts (via the cytoplasmic C-terminal) with ITCH (via the WW domains I and II); the interaction, enhanced by CXCL12, ubiquitinates CXCR4 and leads to its degradation. Interacts with extracellular ubiquitin. Interacts with human cytomegalovirus/HHV- 5 protein UL78. Expressed in numerous tissues, such as peripheral blood leukocytes, spleen, thymus, spinal cord, heart, placenta, lung, liver, skeletal muscle, kidney, pancreas, cerebellum, cerebral cortex and medulla (in microglia as well as in astrocytes), brain microvascular, coronary artery and umbilical cord endothelial cells. Isoform 1 is predominant in all tissues tested. Belongs to the G-protein coupled receptor 1 family. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The CXCR4 cxcr4 (Catalog #AAA176402) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Anti-CXCR4 antibody reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's CXCR4 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Researchers should empirically determine the suitability of the CXCR4 cxcr4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CXCR4, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
