Post Transcriptional Control of Gene Expression (C7131)
15 credits, Level 6
In this module you investigate what happens to a messenger RNA (mRNA) from the time it is synthesised, its subsequent processing, remodelling, export into the cytoplasm and ultimate use to make protein.
While the processing of mRNA molecules is highly regulated, particularly at the levels of transcription and splicing (in eukaryotes), it is the translational machinery that allows the cell to:
- select whether to use the mRNA to make protein at all
- decide which proteins to make
- decide how much protein to make and at what time in the cell cycle.
This regulation is crucial to enable gene expression to be finely tuned with growth and allow cells to respond to environmental cues derived from hormones and nutrients.
You'll take an in-depth look at the molecular mechanisms controlling mRNA utilisation and degradation in eukaryotes focusing largely on translational control and what happens if the cell gets it wrong.
You'll be taught by active researchers providing an up-to-date interpretation of this active and interesting area key to the understanding of growth control and cancer.
