CXCR6


C-X-C chemokine receptor type 6 is a protein that in humans is encoded by the CXCR6 gene. CXCR6 has also recently been designated CD186.
CXCR6 has been identified as an entry coreceptor used by HIV-1 and SIV to enter target cells, in conjunction with CD4. It is a minor coreceptor for HIV-1, nearly all strains of which use CCR5 and/or CXCR4. Most SIV strains can use CXCR6 and recent evidence suggests that in monkeys that serve as the natural hosts of SIV, CXCR6 may be a major coreceptor. CXCR6 was previously known as "Bonzo" and "STRL33" in the HIV/SIV field.
