Understanding the role of eIF4A in gene regulation in health and disease
Webb, Thomas E. (2012) Understanding the role of eIF4A in gene regulation in health and disease. PhD thesis, University of Nottingham.
Eukaryotic initiation factor 4A (eIF4A) is an ATP-dependent RNA helicase responsible for unwinding the secondary structure of mRNAs. In humans, eIF4A exists as three separate paralogs: eIF4AI and eIF4AII possess a high degree of homology while eIF4AIII is distinct. Knockdown of eIF4AII had no effect on the expression of a reporter construct containing a structured RNA hairpin. Knockdown of eIF4AI and treatment with hippuristanol (an eIF4A inhibitor) caused a dramatic reduction in the hairpin-mediated gene. This reporter system was developed as part of this project to act as a screen for eIF4A activity along with an in vitro screening approach.
