About the Project

Control of protein synthesis is critical for normal metabolism, development and responses to stress. One major pathway is called the integrated stress response (ISR) and centres on translational control of the general protein synthesis factor eIF2B via the phosphorylation of eIF2 [1,2]. When dysregulated this can contribute to a range of diseases including the progression of some cancers [3]. The structural analysis of several large protein complexes involved in the activation and resetting the ISR are not yet known. In addition there are viruses that overcome ISR controls during infection by the synthesis of proteins that modulate the ISR at distinct steps. In this project the student will learn to purify proteins, assay their activities and apply modern cryo-EM analyses to one or more important complexes involved in regulating the ISR.

The student will make use known information and available methods to express and purify one or more complex for structural and functional evaluation to provide insight into the function of this important and central stress responsive regulatory pathway.

We will use cryoEM to determine and interpret the molecular interactions between eIF2 and other bound factors, as well as uncover larger molecular rearrangements induced by complex formation.

Further information will be available on request

Entry Requirements

Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree (or equivalent) in a related area/subject. Candidates with previous laboratory experience, particularly in cell culture and molecular biology, are particularly encouraged to apply.

How To Apply

For information on how to apply for this project, please visit the Faculty of Biology, Medicine and Health Doctoral Academy website (https://www.bmh.manchester.ac.uk/study/research/apply/). Informal enquiries may be made directly to the primary supervisor. On the online application form select PhD Genetics

For international students, we also offer a unique 4 year PhD programme that gives you the opportunity to undertake an accredited Teaching Certificate whilst carrying out an independent research project across a range of biological, medical and health sciences.
