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). ...
Post-transcriptional processes affecting mRNA availability The amount of mRNAs available for translation can be affected at different steps of the process of RNA maturation, ranging RNA transcription to splicing, from transport to translation initiation, and degradation by RNAi. Two main families of prot...
Since this review is practical in nature, I will emphasize the cis-acting elements of a gene which control post-transcriptional RNA processing and translation; I will not discuss the trans-acting factors which must interact with the cis-elements to effect post-transcriptional and translational ...
Post-translational modifications are modifications that occur on a protein, catalysed by enzymes, after its translation by ribosomes is complete. Post-translational modification generally refers to the addition of a functional group covalently to a protein as in phosphorylation and neddylation, but also...
Other T4 post-transcriptional control systems RNA structure at translation initiation regions RNA structure influences translation initiation of T4 mRNAs, especially as they target protein binding in translational repression (i.e., gp32 and gp43 above; [65,95]). In addition, some T4 mRNAs form in...

miRNAs control gene expression post-transcriptionallly, by hybridizing to target mRNAs and thereby regulating their translation or stability. By targeting dozens or even hundreds of different mRNAs, individual miRNAs have the potential to fine-tune or modulate the expression of genes that participate in...

HuR: post-transcriptional paths to malignancy.The RNA-binding protein HuR regulates the stability and translation of target mRNAs. While no HuR mutations have been found in cancer, a link between HuR and malignant transformation has been suggested in cancers of the breast, colon, lung, and ovary...
