过一些化学修饰才可以得到。转录后加工转录后的加工(posttranscriptionalmodification)(一)tRNA的加工 tRNA的加工分成3个阶段(1)“斩头”,形成5′末端;(2)去尾,形成3′-OH末端。(3)修饰:通过甲基化酶,硫醇酶,假尿 嘧啶核苷化酶等进行修饰,如氨基酸臂的4-硫尿苷(4tu),D臂的2甲基鸟苷(2mG),Tψ...
Post-transcriptional modification is a process in cell biology by which, in eukaryotic cells, primary transcript RNA is converted into mature RNA. A notable example is the conversion of precursor messenger RNA into mature messenger RNA (mRNA), which includes splicing and occurs prior to protein ...

discuss the structure, function and regulation of S-acylation and deacylation enzymes and describe how this post-transcriptional modification precisely controls protein–cell membrane interactions. Potential therapeutic applications of S-acylation are also highlighted. Francisco S. Mesquita Laurence Abrami F....

Post-translational modifications are key mechanisms to increase proteomic diversity.While the genome comprises 20,000 to 25,000 genes, the proteome is estimated to encompass over 1 million proteins. Changes at the transcriptional and ...
Two new studies advance understanding of this RNA modification. One shows that m6A modification of nascent messenger RNA promotes transcription by recruiting the histone H3 K9 demethylase KDM3B. Another study identifies genetic variants that affect m6A deposition and human disease....
The first is mRNA processing or post-transcriptional modification . It occurs between transcription and translation in eukaryotes, but does not occur in bacteria. The process involves a series of modifications that the RNA transcript (hnRNA) must undergo before it can be translated (Fig. 5.1). ...
