Background
ULBP-1, also known as MULT-1 (mouse UL16-binding protein-like Transcript 1), is a 53 kDa, MHC Class I-like molecule that belongs to the mouse family of NKG2D ligands (1‑4). It is a type I transmembrane glycoprotein that is synthesized as a 334 amino acid (aa) precursor. It contains a 25 aa signal sequence, a 186 aa extracellular region, a 19 aa transmembrane segment and a 104 aa cytoplasmic tail (2). The extracellular region contains an alpha 1 and alpha 2 like domain with two intrachain disulfide bonds. ULBP-1 is distantly related to other human and mouse NKG2D ligands, and more distantly related to the MHC class I proteins (3). Unlike most NKG2D ligands, transcripts for ULBP-1 have been detected in a wide variety of mouse tissues and tumor cells lines (3). The receptor for ULBP-1 is NKG2D, a 35 kDa C-type lectin that is found on mouse NK cells, activated CD8+ T cells, epidermal gamma δ T cells, and activated macrophages (1, 5, 6, 7). Recombinant ULBP-1 protein binds to NKG2D with high affinity (KD = 6 nM) (2). Although an activating receptor, general cellular responses to NKG2D ligation depend upon the isoform of NKG2D and the cell type (5). Exposure to immobilized ULBP-1 or ULBP-1-transfected cells elicits IFN-gamma production by NK cells (3). Ectopic expression of ULBP-1 on the RMA mouse tumor cell line leads to tumor rejection in syngeneic mice (3).
