An HLA-B44 cDNA clone was identified in a cDNA library constructed from an HLA-B44 homozygous cell line. The DNA sequence was determined and was found to contain the complete coding sequence but for (probably) the three N-terminal codons. Comparisons of the derived amino acid sequence with other HLA-A and -B locus amino acid sequences revealed four HLA-B44-specific substitutions including a new polymorphic site. Regions of strong sequence conservation for HLA-B-locus products were found at the nucleotide and amino acid levels.
在一个由HLA - B44纯合细胞系构建的cDNA文库中鉴定出一个HLA - B44 cDNA克隆。测定了其DNA序列,发现其包含完整的编码序列,但可能缺少三个N端密码子。将推导的氨基酸序列与其他HLA - A和 - B位点氨基酸序列进行比较,发现了四个HLA - B44特异性取代,包括一个新的多态性位点。在核苷酸和氨基酸水平上发现了HLA - B位点产物的强序列保守区域。
