Gene Regulation and Cellular Biotechnology

Overview

The regulated expression of genes is central to all forms of life. Our research group brings together researchers who study (1) processes central to the expression of genes (transcription, splicing and translation) and the regulatory mechanisms that control these events (modifications, interactions and localisation and (2) the impact of environmental cues and stresses on cellular functions. We also apply genetic engineering technologies to mammalian, plant and microbial cells for biotechnology applications including strategies to enhance production of biopharmaceuticals, therapeutics and for biofuel production. Our work integrates molecular biology, biochemistry, genetics, cell biology, cellular imaging and systems biology techniques.

Research group leader: Dr Graham Pavitt
