Protein Information
Name CX3CR1
Synonyms CMKBRL1, GPR13
Function Receptor for the CX3C chemokine fractalkine and mediates both its adhesive and migratory functions. Acts as coreceptor with CD4 for HIV-1 virus envelope protein (in vitro). Isoform 2 and isoform 3 seem to be more potent HIV-1 coreceptors than isoform 1.
Cellular Location Cell membrane; Multi-pass membrane protein.
Tissue Location Expressed in lymphoid and neural tissues.

CX3CR1 Antibody: CX3CR1 is one of the chemokine receptors that are required as coreceptors for HIV infection. The genes encoding human, mouse, and rat CX3CR1 were cloned and designated V28 and CMKBRL1, CX3CR1, and RBS11, respectively. The encoded seven transmembrane protein was initially identified as the receptor for the transmembrane molecule fractalkine, and renamed CX3CR1. CX3CR1 is known to serve as a coreceptor for HIV-1 and HIV-2 envelope fusion and virus infection, which can be inhibited by fractokine. CX3CR1 mediates leukocyte migration and adhesion. CX3CR1 is expressed in a variety of human tissues and cell lines.
