PolyclonalDescripción
Chemokine C-X-C-Motif Receptor 4 (CXCR4) Antibody is a Rabbit Polyclonal antibody for the detection of CXCR4. C-X-C chemokine receptor type 4 (CXCR4) is a widely expressed G protein-coupled seven-transmembrane receptor. CXCL12/SDF-1 is the biological ligand for CXCR4. The binding of CXCL12 to CXCR4 induces intracellular signaling through several divergent pathways initiating signals related to chemotaxis, cell survival and/or proliferation, increase in intracellular calcium, and gene transcription (PMID: 20484021). CXCR4 also functions as a coreceptor for HIV-1 entry (PMID: 9427609). CXCR4 has a calculated molecular weight of 40 kDa. In addition to the predicted species of 45-47 kDa for glycosylated CXCR4 monomers, due to ubiquitination, dimeration, and different degrees of glycosylation, additional species can also exist and have been reported in some researches, including 67 kDa (PMID: 23917520), 55, 67, 87 kDa (PMID: 20028517), 80 kDa (PMID: 10506573), 47, 50, 62, and 98 kDa (PMID: 16204649).
Background
CXCR4 is a widely expressed G protein-coupled receptor that binds stromal cell-derived factor-1 (SDF-1/CXCL12), playing a key role in hematopoiesis, organ development, and immune cell trafficking. It is highly expressed on hematopoietic stem cells, lymphocytes, and endothelial cells. CXCR4 activation triggers pathways such as PI3K/Akt, MAPK, and JAK/STAT, promoting cell survival, migration, and proliferation. In the immune system, CXCR4 guides leukocyte migration to lymphoid tissues and inflammatory sites, facilitating immune surveillance. It is critical for embryonic development, particularly in the nervous, cardiovascular, and hematopoietic systems. In cancer, CXCR4 is overexpressed in many malignancies, including breast, lung, and pancreatic cancers, where it promotes tumor progression, metastasis, and angiogenesis by interacting with the CXCL12 gradient. CXCR4 also enhances the homing of cancer cells to distant organs, such as the bone marrow, contributing to metastasis and therapy resistance. In HIV infection, CXCR4 acts as a co-receptor for viral entry into T cells, playing a role in disease progression to AIDS. Targeting CXCR4 with antagonists like plerixafor is a therapeutic strategy for stem cell mobilization, HIV treatment, and anti-cancer therapy. Dysregulation of CXCR4 signaling is linked to inflammatory diseases, immune deficiencies, and metastatic cancer, highlighting its importance in immune regulation and disease pathogenesis.
