CD184 (CXCR4) Antibody, anti-human, Vio® Bright V423, REAfinity™，130-127-227，美天旎

Clone REA649 recognizes the human CD184 antigen, a multi-pass membrane protein, also known as C-X-C chemokine receptor type 4 (CXCR4), leukocyte-derived seven transmembrane domain receptor (LESTR), or fusin. CD184 is ubiquitously expressed on blood and tissue cells. It mediates chemotaxis in mature and progenitor blood cells and is important for B lymphopoiesis, myelopoiesis, and cardiogenesis. CD184 exclusively interacts with the endogenous ligand CXCL12. Binding of CXCL12 transduces a signal by increasing intracellular calcium ion levels and enhancing MAPK1/MAPK3 activation. Although CXCL12 is the only known chemokine that binds CD184, recent studies suggest that extracellular ubiquitin also acts as an immune modulator through CD184-mediated signaling. CD184 is a coreceptor for HIV entry by promoting Env-mediated fusion of the virus.

Additional information: Clone REA649 displays negligible binding to Fc receptors.
