Preparation and Storage

Background: B7-H6

B7-H6 is a 55 kDa glycosylated member of the B7 family of immune costimulatory proteins (1, 2). Mature B7-H6 consists of an extracellular domain (ECD) that with one Ig-like V domain and one Ig-like C1 domain, a transmembrane segment, and a cytoplasmic domain that contains one ITIM, one SH2, and one SH3 motif (3). Both of the Ig-like domains carry N-linked glycosylation (4). Within the ECD, cynomolgous B7-H6 shares 81%, 81%, 77% and 80% amino acid sequence identity with chimpanzee, orangutan, gibbon, and human B7-H6, respectively. Orthologs in mouse and rat have not been identified. The Ig-like V domain mediates 1:1 stoichiometric binding of B7-H6 to NKp30 expressed on NK cells (4, 5). It does not show binding to NKp44, NKp46, or NKG2D (3, 6). Ligation of NKp30 by B7-H6 induces NK cell activation and target cell cytolysis (3). B7-H6 is expressed on a wide range of hematopoietic, carcinoma, and melanoma tumor cells, which is consistent with the detection of NKp30 binding sites on many tumors (3, 7). B7-H6 is up-regulated on inflammatory monocytes and neutrophils, and a 30 kDa soluble fragment can be released by ADAM-10 or ADAM-17 mediated shedding (8, 9). The expression of B7-H6 on tumor cells correlates with cancer progression and patient's survival in human ovarian cancer (10).
