ULBP1, also known as NKG2D ligand 1, is a member of a family of cell-surface proteins that function as ligands for human NKG2D. It is unconventional MHC class I-like molecules exploited by viruses and cancer. Its ligand Methylation contributes to immune system evasion in acute myeloid leukemia. It is independent predictors of good prognosis in cervical cancer. Source: Recombinant protein corresponding to aa26-216 from human ULBP1, fused to His-Tag at C-terminal, expressed in insect cell.
