Target Bioclass
Immunoglobulin
Family
MHC class I family, MIC subfamily
Subcellular location
Cell membrane
Function
Seems to have no role in antigen presentation. Acts as a stress-induced self-antigen that is recognized by gamma delta T cells. Ligand for the KLRK1/NKG2D receptor. Binding to KLRK1 leads to cell lysis.
