Putative amino acid sequence of

B7-H2 gene and alignment of the B7 family members. (A) Predicted amino acid sequence of human B7-H2. The predicated signal peptide, Ig V-like domain, Ig C-like domain, transmembrane region, and the potential N-linked glycosylation site (*) are indicated. The nucleic acid and amino acid sequences of B7-H2 are available from GeneBank under accession number AF289028. (B) Alignment of the B7-H2 with B7-1, B7-2, and B7-H1. Identical amino acid residues are shaded in bold and conserved residues are boxed. Cysteine residues that may be important in the forming of disulfide bond inside Ig V or Ig C domains are indicated (*).
