Human CD160/BY55 Protein, ECD (Extracellular Domain), Fc-fusion, Recombinant

Description

 

CD160, also known as Natural killer cell receptor BY55, is a GPI-anchored cell surface protein. As a member of the Ig (immunoglobulin) superfamily, CD160 contains 1 Ig-like V-type domain in its extracellular region. Its expression is restricted to functional NK and T cytotoxic lymphocytes. CD160 is expressed as a disulfide-linked multimer on the cell surface. CD160 is a receptor showing broad specificity for both classical and non-classical MHC class I molecules. CD160 is known to bind HLA-G1, HLA-C, and HVEM. CD160 binding to HLA-G1 initiates apoptosis. CD160 signaling in response to HLA-C binding promotes cytokine secretion. CD160 is up regulated on CD4+ T cells following activation. CD160 may function as a co-activator receptor for CD3-induced proliferation of T cells and CD4+ CD160+ lymphocyte subset may play a role in the pathogenesis of skin inflammation. CD160 engagement by HVEM (expressed by APC) serves to block a simultaneous LIGHT stimulation of HVEM that promotes receptor expression and cytokine release. Activated NK lymphocytes may release a soluble form of CD160 that impairs the MHC-I-specific cytotoxic T lymphocyte responsiveness.
