Description | CD160 is a 27 kD GPI-anchored glycoprotein also known as BY55, NK1, and NK28. A member the Ig superfamily, CD160 exists as a disulfide-bond multimer, expressed on the surface of a subpopulation of NK cells, γ/δ T cells, subset of CD8+ T cells, and intestinal intraepithelial lymphocytes (IEL). CD160 plays costimulatory roles through binding to classical and nonclassical MHC-I molecules. |
