CD160 antigen(1-158)

General information on CD160 antigen (CD160):

The CD160 antigen is a protein encoded by the CD160 gene in humans. CD160 is a glycoprotein that was originally identified with the monoclonal antibody BY55. Its expression is strictly related to peripheral blood NK cells and cytolytically active CD8 T lymphocytes. The CD160 cDNA sequence can be predicted to be rich in 18-colored glycosylphosphatidylinositol amino acids, with a single Ig-like domain that is weakly homologous to the KIR2DL4 molecule. CD160 is expressed on the cell surface as a multimer with tightly bound disulfide bonds. Northern blot analysis showed that the CD160 mRNA was 1.5 and 1.6 kb, and its expression was very limited to circulating NK and T cells, spleen, and small intestine. In NK cells, CD160 is expressed by CD56dimCD16 + cells, while in circulating T cells, its expression is mainly limited to cells carrying TCRgd and TCRab + CD8brightCD95 + CD56 + CD28-CD27-CD27 cells. In tissue, CD160 is expressed on all intestinal intraepithelial lymphocytes. CD160 exhibits broad specificity for the binding of classical and unconventional MHC class I molecules.
