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 ...
转录后的加工（posttranscriptionalmodification）（1）减少部分片段：如切除5′端前导序列，3′端拖尾序列和中部的内含子；（2）增加部分片段：5′加帽，3′加poly(A)，归巢和通过编辑加入一些碱基；（3）修饰：对某些碱基进行甲基化等。转录后加工转录后的加工（posttranscriptionalmodification）第一节tRNA和rRNA的...

Post-transcriptional modification of serum creatine kinase in infected intensive care patients. Clin Chim Acta 1990;187(2):115-24.Delanghe, J.R., De Buyzere, M.L., De Scheerder, I.K., Van Rostenberghe, H.L., Faust, U., Rodenbach, J.M., Kruse-Jarres, J.D., and Wieme, R....
Although modifications play essential roles in tRNA biology, methods to directly detect their introduction during tRNA maturation are rare and do not easily provide information on the temporality of modification events. To obtain information on the tRNA maturation process, we have developed a methodology...
N6-methyladenosine (m6A) is a prevalent post-transcriptional modification in mammalian mRNA. m6A is enriched in consensus sequences within long exons, near stop codons and at the 3′ untranslated regions (3′ UTRs). m6A is the first confirmed reversible mRNA modification with dedicated methyltransfe...
This post- transcriptional modification prevents binding of the macrolides to the ribosome and renders cells resistant to very high concentrations of these drugs. The same modification confers resistance to two other classes of antibiotics, lincosamides and streptogramins B, whose binding sites in ...
