用人类白细胞抗原E特异性寡核苷酸探针研究人类白细胞抗原E的表达。该探针检测到两个大小分别为1.8kb和2.7kb的HLA-E转录本,它们在所研究的所有组织和细胞系中以不同的比例存在。我们证明,替代的Poly(A)位点的使用解释了这两个HLA-E mRNA物种的不同调控。序列分析表明,3‘非翻译区的基因和c DNA在3’端非翻译区具有同源性。S1核酸酶保护实验证实这两个人类白细胞抗原E转录本不是选择性剪接产物。将CD3.14与人β2 m共同导入小鼠骨髓瘤细胞系P3X63-Ag8.653,间接免疫荧光检测到HLAI类重链的表达,而将其导入表达人β2m的小鼠L细胞株J27,细胞表面表达阴性。转染体的细胞表面标记和单态HLAI类特异性抗体或抗人β2m抗体的免疫沉淀证实了细胞表面存在一条HLA-E H链。这些结果表明,人类白细胞抗原-E基因编码了一条可在细胞表面表达的I类H链。
An HLA-E-specific oligonucleotide probe was used to study the expression of HLA-E. This probe detects two HLA-E transcripts, 1.8 and 2.7 kb in size, which are present in varying ratios in all tissues and cell lines investigated. We demonstrate that alternative poly(A) site usage accounts for the differential regulation of the two HLA-E mRNA species. Sequence analysis of three cDNA clones, representing the two transcripts of HLA-E, and of an HLA-E gene encoded by cosmid cd3.14, revealed identity of gene and cDNA in the 3' untranslated region. S1 nuclease protection assays confirmed that the two HLA-E transcripts are not alternative splicing products. Introduction of cd3.14, together with human beta 2 m into the murine myeloma cell line P3X63-Ag8.653, resulted in a cell surface expression of an HLA-class I heavy chain detectable by indirect immunofluorescence whereas transfection into the human beta 2m expressing mouse L cell line, J27 was negative with regard to cell surface expression. Cell surface labeling of transfectants and immunoprecipitation with a monomorphic HLA class I-specific antibody or an antibody against human beta 2m confirmed the presence of an HLA-E H chain on the cell surface. These results indicate that the HLA-E gene codes for a class I H chain that can be expressed on the cell surface.
