A cDNA library constructed from liver mRNA of DBA/2 (H-2d) mice has been screened with H-2-specific probes. The nucleotide sequence of one clone (pH-2d-24) indicates that it derives from an H-2 gene with an unexpected exon-intron organization. Nucleotide sequence comparisons suggest that two distinct mRNAs are produced from a single H-2Kd gene by a mechanism involving the use of alternative splicing sites in its 5' region. pH-2d-24 carries an open reading frame encoding a thus-far-undescribed polypeptide product identical to an H-2Kd-molecule, except for the NH2-terminal half of the first domain.
用H - 2特异性探针筛选了由DBA/2(H - 2d)小鼠肝脏mRNA构建的cDNA文库。一个克隆(pH - 2d - 24)的核苷酸序列表明它源自一个具有意外外显子 - 内含子组织的H - 2基因。核苷酸序列比较表明,通过一种涉及在其5'区域使用可变剪接位点的机制,从单个H - 2Kd基因产生了两种不同的mRNA。pH - 2d - 24携带一个开放阅读框,该阅读框编码一种迄今为止未描述的多肽产物,该产物与H - 2Kd分子相同,除了第一个结构域的NH2末端一半。
