Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Mossanen-Parsi, Amir, once mentioned the application of 36315-01-2, Name is 2-Amino-4,6-dimethoxypyrimidine, molecular formula is C6H9N3O2, molecular weight is 155.16, MDL number is MFCD00038832, category is pyrimidines. Now introduce a scientific discovery about this category, COA of Formula: C6H9N3O2.
Histone mRNA is subject to 3 ‘ uridylation and re-adenylation in Aspergillus nidulans
The role of post-transcriptional RNA modification is of growing interest. One example is the addition of non-templated uridine residues to the 3 ‘ end of transcripts. In mammalian systems, uridylation is integral to cell cycle control of histone mRNA levels. This regulatory mechanism is dependent on the nonsense-mediated decay (NMD) component, Upf1, which promotes histone mRNA uridylation and degradation in response to the arrest of DNA synthesis. We have identified a similar system in Aspergillus nidulans, where Upf1 is required for the regulation of histone mRNA levels. However, other NMD components are also implicated, distinguishing it from the mammalian system. As in human cells, 3 ‘ uridylation of histone mRNA is induced upon replication arrest. Disruption of this 3 ‘ tagging has a significant but limited effect on histone transcript regulation, consistent with multiple mechanisms acting to regulate mRNA levels. Interestingly, 3 ‘ end degraded transcripts are also subject to re-adenylation. Both mRNA pyrimidine tagging and re-adenylation are dependent on the same terminal-nucleotidyltransferases, CutA, and CutB, and we show this is consistent with the in vitro activities of both enzymes. Based on these data we argue that mRNA 3 ‘ tagging has diverse and distinct roles associated with transcript degradation, functionality and regulation.
