从人垂体 cDNA 文库中分离的 cDNA 克隆的序列推导出神经内分泌蛋白 7B2 的两种类型的 mRNA。一种类型缺少另一种类型中存在的 Ala100 密码子。这种差异位于人类 7B2 基因内的一个内含子位点,并且可以通过两个相隔三个核苷酸的替代受体剪接位点的转录利用来解释。通过聚合酶链式反应扩增的 DNA 片段的异双链分析表明,这种 7B2 mRNA 二态性发生在几种人类内分泌组织以及其他物种中,表明 7B2 基因转录本的交替加工可能是其表达的内在机制,并且可能是一些未知的生物学功能的基础。
Two types of mRNAs for neuroendocrine protein 7B2 were deduced from the sequence of cDNAs clones isolated from a human pituitary cDNA library. One type lacks an Ala100codon present in the other. The difference is located at an intron site within the human 7B2 gene and can be explained by the transcriptional utilization of two alternate acceptor splice sites, three nucleotides apart. Heteroduplex analysis of DNA fragments amplified by the polymerase chain reaction indicated that this 7B2 mRNA dimorphism occurs in several human endocrine tissues as well as in other species, suggesting that the alternate processing of 7B2 gene transcripts may be an intrinsic mechanism of its expression and could underlie some yet unknown biological functions.
