| Description |
This recombinant human CXCR4 virus-like particle (VLP) is a nanodimensional structure built from viral structural constituents in the form of recombinant proteins synthesized in mammalian cells. Its expression region encodes the full-length human CXCR4 protein (1-352aa). It carries a 10xHis-tag at the C-terminus. Its endotoxin level is less than 1.0 EU/ug measured by the LAL method. It has been validated to be biologically active. In the functional ELISA, this recombinant human CXCR4 VLP can bind to the anti-CXCR4 recombinant antibody, with the EC50 of 101.7-253.6 ng/mL. CXCR4 is a pleiotropic chemokine receptor that regulates a variety of physiological processes through its ligand CXCL12, including immune response, hematopoiesis, developmental processes, and pro-tumorigenic effects. It is almost expressed in all types of hematopoietic cells. The CXCR4 axis stimulates EGFR, MAPK, PI3K/AKT, Wnt/β-catenin, and NF-κB related pathways, which are involved in tumor development, survival, invasion, and homing. CXCR4/CXCL12 signaling is also involved in metastasis. Currently, CXCR4 has been detected in 23 different types of tumors, which is the most commonly expressed chemokine receptor in tumor cells and is associated with the prognosis of patients. The development of CXCR4 antagonists and the down-regulation of CXCR4 expression in cancer cells is of great significance for the treatment of related diseases. |

| 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. Involved in the AKT signaling cascade. Plays a role in regulation of cell migration, e.g. during wound healing. Acts as a receptor for extracellular ubiquitin; leading to enhanced intracellular calcium ions and reduced cellular cAMP levels. Binds bacterial lipopolysaccharide (LPS) et mediates LPS-induced inflammatory response, including TNF secretion by monocytes. 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.; (Microbial infection) Acts as a coreceptor (CD4 being the primary receptor) for human immunodeficiency virus-1/HIV-1 X4 isolates and as a primary receptor for some HIV-2 isolates. Promotes Env-mediated fusion of the virus.

| Subcellular Location | Cell membrane; Multi-pass membrane protein. Cell junction. Early endosome. Late endosome. Lysosome. Note=In unstimulated cells, diffuse pattern on plasma membrane. On agonist stimulation, colocalizes with ITCH at the plasma membrane where it becomes ubiquitinated. In the presence of antigen, distributes to the immunological synapse forming at the T-cell-APC contact area, where it localizes at the peripheral and distal supramolecular activation cluster (SMAC). |
