UTR代表了RNA EXON的非蛋白质编码部分。目前,UTRs不支持该DTD以外的TIGR数据类型,它们的存在仅为了便于外部数据分析。 5'UTR :region at the 5' end of a mature transcript (preceding the initiation codon) that is not translated into a protein 3'UTR: 3‘端非翻译区,也就是mRNA两端的非编码片段 顺便...
5' UTR,3' UTR 叫作 untranslated region ,而 introns 叫作non-coding RNA。一段基因序列上包含外显子和内含子,转录的时候,pre-RNA就是前体RAN上会有内含子和外显子,成为成熟RNA时,内含子已经被剪切了,只保留外显子,所以内含子叫作非编码RNA(non-coding RNA)。但成熟的RNA上也是有一部分序列并不翻译成蛋白...
几个3' UTR 还包含富含腺嘌呤-尿嘧啶 (AU) 的元素序列,如 (AAUAAA),它指示将称为聚 (A) 尾巴的腺嘌呤残基添加到 mRNA 转录物的末端。 ▲The 3′ UTR also contains sequences that promote proteins association with mRNA with the cell ...
