How is the regulation of cell activity at the level of the transcription process?
June 27, 2020
I – pre-transcriptional (DNA methylation) – cell cycle; chromatin spiralization in eukaryotes
a) initiation (promoters + regulatory proteins) b) termination (attenuation and antiterms and nation)
III – post-transcriptional:
a) mRNA stability (rpoS)
b) broadcast initiation (cold shock)
IV – post-translational; regulation of metabolism through protein-protein interactions and protein modification; allosteric regulation (chemotaxis).
