SP1286P recognises the orphan G protein-coupled chemokine receptor CXCR6, also known as CDw186. CXCR6 has been identified as a co-receptor for simian immunodeficiency virus (SIV), HIV-2 and HIV-1. Lymphoid tissues and activated peripheral blood lymphocytes express CXCR6 mRNA.
Purification
Affinity purified immunoglobulin fraction
Immunogen
Peptide corresponding to aa 11 to 25 of human CXCR6/CDw186 (NT)
Human Immunodeficiency Virus (HIV) and Simian Immunodeficiency Virus (SIV) require coreceptors to enter and infect target cells. They are dependent upon an interaction between the viral envelope glycoprotein with T cell antigen T4 (CD4) and a G protein coupled receptor (GPCR). HIV1 infection relies upon interaction with a chemokine receptor, usually chemokine (C-C) receptor 5 (CCR5). During progression of the infection, the virus tends to rely upon chemokine (C-X-C) receptor 4 (CXCR4). SIV also utilizes CCR5 in the early stages of infection, but during progression it tends to rely on two orphan GPCR's named chemokine (C-X-C) receptor 6 (Bonzo) and G protein coupled receptor 15 (BOB/GRP15). Bonzo mRNA expression has been localized to lymphoid tissues and activated peripheral blood lymphocytes.Synonyms: BONZO, CDw186, CXC-R6, CXCR-6, G-protein coupled receptor STRL33, G-protein coupled receptor bonzo, STRL33, TYMSTR
