Research AreasImmunology

Function

(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.

Biological Context

Subcellular Location: Cell membrane (Multi-pass membrane protein); Cell junction; Early endosome; Late endosome; Lysosome
Tissue Specificity: 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
Disease Association: WHIM syndrome 1 (WHIMS1) : An autosomal dominant immunologic disease characterized by neutropenia, hypogammaglobulinemia and extensive human papillomavirus (HPV) infection. Despite the peripheral neutropenia, bone marrow aspirates from affected individuals contain abundant mature myeloid cells, a condition termed myelokathexis. [The disease is caused by variants affecting the gene represented in this entry] | [CXCR4 mutations play a role in the pathogenesis of Waldenstroem macroglobulinemia (WM) and influence disease presentation and outcome, as well as response to therapy. WM is a B-cell lymphoma characterized by accumulation of malignant lymphoplasmacytic cells in the bone marrow, lymph nodes and spleen, and hypersecretion of monoclonal immunoglobulin M (IgM). Excess IgM production results in serum hyperviscosity, tissue infiltration, and autoimmune-related pathology]
