ab208129 staining CXCR4 in Jurkat cells. The cells were fixed with 80% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab208129 at 1/50 dilution (shown in red) and ab195887, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 488), at 1/250 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

This product also gave a positive signal under the same testing conditions in Jurkat cells fixed with 4% formaldehyde (10 min).

Supplementary information

CXCR4 also known as C-X-C chemokine receptor type 4 is a G protein-coupled receptor that is involved in signal transduction. It has a molecular weight of approximately 41 kDa. CXCR4 is ubiquitously expressed across various tissues including immune cells like T and B lymphocytes as well as in bone marrow brain and heart. It binds specifically with the ligand CXCL12 also known as stromal cell-derived factor 1 (SDF-1) facilitating responses such as cell migration and proliferation.
Biological function summary

CXCR4 plays an important role in the immune system hematopoiesis and angiogenesis. It does not function alone and is often part of a larger protein complex where it recruits and activates other G proteins. The receptor mediates chemotactic responses directing cells to sites of inflammation or injury. Its interaction with CXCL12 is critical for maintaining immune surveillance aiding in the movement and positioning of immune cells.

Pathways

CXCR4 integrates into significant cellular signaling pathways such as the PI3K/AKT pathway and the MAPK pathway. It collaborates closely with signaling proteins like AKT1 and MAPK1 impacting cell survival and growth. These pathways are essential for various cellular functions including cell cycle progression and apoptosis regulation. The cross-talk between CXCR4 and these pathways underlines its influence on cell fate decisions.

CXCR4 is implicated in cancer metastasis and HIV entry into cells. Overexpression of CXCR4 is observed in several cancers contributing to tumor growth and metastasis. The interaction between CXCR4 and CXCL12 facilitates the infiltration and spread of cancer cells. Additionally in HIV CXCR4 serves as a coreceptor along with CD4 allowing the virus to enter and infect host cells. Both cancer and HIV illustrate CXCR4's central role in disease progression and pathogenesis.

Target data

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 (PubMed : 10452968, PubMed : 18799424, PubMed : 24912431, PubMed : 28978524). Involved in the AKT signaling cascade (PubMed : 24912431). Plays a role in regulation of cell migration, e.g. during wound healing (PubMed : 28978524). Acts as a receptor for extracellular ubiquitin; leading to enhanced intracellular calcium ions and reduced cellular cAMP levels (PubMed : 20228059). Binds bacterial lipopolysaccharide (LPS) et mediates LPS-induced inflammatory response, including TNF secretion by monocytes (PubMed : 11276205). 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 (By similarity).. (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 (PubMed : 10074122, PubMed : 10756055, PubMed : 8849450, PubMed : 8929542, PubMed : 9427609).
