Our research aims to answer fundamental questions about how cells and organisms work at the molecular and biochemical level. We study the structures and properties of DNA, RNA and protein molecules, and how these molecules interact within cells to form complex functional networks. We are also working towards applications of our knowledge to address important real-world problems.

Mechanisms and applications of DNA site-specific recombinases
Outline & aim
Site-specific recombinases are enzymes that promote rearrangements of DNA molecules, by cutting and rejoining DNA strands at precise places within short target sequences (sites). For example, a specific piece of DNA can be cut out of a larger molecule, or its orientation can be reversed. Our research group aims to understand in detail how recombinases catalyse these reactions, and how they are controlled. To do this we use high-resolution structural data and advanced techniques for laboratory analysis. Site-specific recombinases have tremendous potential as tools for manipulating DNA in the fields of biotechnology, synthetic biology and gene therapy. We are investigating how to engineer “designer recombinases” that are suitable for these purposes, and how to use them for novel applications.
The aim of the research project will be to advance our understanding in one of the areas outlined above. For example, the project might be an investigation of the mechanism of DNA strand cutting and rejoining, using novel “single-molecule” methodologies, or to develop novel designer recombinases suitable for targeting specific genes in a living organism for deletion or modification.

Defining the mechanism of abscission
Outline & aim
ESCRT proteins mediate membrane scission events involved in the down-regulation of ubiquitin-labelled receptors via the multivesicular body (MVB) pathway and in HIV budding from host cells. In addition, ESCRT proteins play a role in abscission, the final stage of cytokinesis. The ESCRT machinery is composed of four complexes: ESCRT-0, -I, -II and -III; and the modular composition of the ESCRT machinery is reflected in its various functions. At a precise time during cytokinesis, the ESCRT-I protein TSG101 and ESCRT-associated protein ALIX are recruited to the midbody through interactions with CEP55; TSG101 and ALIX in turn recruit ESCRT-III components. Thereafter, by a mechanism still not completely understood, ESCRT-III redistributes to the putative abscission sites, microtubules are severed and the daughter cells separate. However, the mechanisms by which this selective and specific redistribution of ESCRT proteins is regulated in space and time remain largely unsolved.
ESCRT components are phosphoproteins, so we reasoned that kinases and phosphatases are likely candidates for ESCRT regulation. We hypothesised that polo and aurora kinases and Cdc14 phosphatase may be potential regulators of ESCRT function due to their significant roles in controlling cytokinesis. This aspect of mitotic regulation of
ESCRT function will be investigated in this project, as we have shown that these kinases and phosphatases play a role; our challenge now is to define that role and to determine whether similar mechanisms operate in mammalian cells. This interface between signalling and trafficking is an important and active research theme worldwide, and you will join an active and collaborative group well versed in all the training aspects required for successful completion of a PhD.
The aim of the project is to define the role of aurora kinase, polo-like kinase and Cdc14 on ESCRT function in yeast and mammalian cells.

Protein folding and secretion in mammalian cells
Outline & aim
The ability of cells to correctly fold and assemble proteins is the final stage in protein synthesis. Protein folding requires a subset of proteins able to either catalyse folding reactions or act as molecular chaperones preventing non-productive protein aggregation. The inability of cells to carry out the folding process results in some of the most catastrophic mammalian diseases such as cystic fibrosis, Alzheimer's and CJD.
We aim to understand how cells fold and assemble proteins we are studying this process in mammalian cells using a combination of cell biological and biochemical techniques.

The role of EPAC1 in the control of cytokine signalling in vascular endothelial cells
Outline & aims
We and others [1-3] have found that the cyclic AMP-activated signalling protein EPAC1 (exchange protein activated by cyclic AMP 1) promotes protective functions in vascular endothelial cells (VECs), including promotion of endothelial barrier function and induction of protein suppressors of cytokine signalling (eg SOCS3), and therefore plays a vital role in maintaining the health of the vasculature.
It is now clear that interactions with cellular binding proteins determine both the intracellular location and enzyme activity of EPAC1. For example, the cytoskeleton-associated, MAP1a-LC2 protein , recruits EPAC1 to microtubules and enhances its activity, whereas the nuclear-localised SUMO ligase, RanBP2 [5,6], suppresses EPAC1 activity at the nuclear pore complex.
Our aim now is to fully understand these control mechanisms with the long term goal of devising new therapies based on modulating protein interactions with EPAC1. Central to this goal is the new observation that EPAC1 becomes SUMOylated within the regulatory cyclic nucleotide binding domain (CNBD). Since the CNBD is responsible for direct activation by cyclic AMP and is also responsible for cytoskeletal recruitment through MAP1a-LC2, then SUMOylation represents a powerful new control mechanism for controlling EPAC1 localisation and activity.The student will therefore determine:
- The effects of SUMOylation on EPAC1 activity, subcellular localisation and interaction with regulatory proteins
- Determine the role of EPAC1 SUMOylation on the regulation of cytokine signalling in vascular endothelial cells
- cell culture
- light microscopy
- confocal microscopy
- reporter genes
- western blotting

Our biochemists and molecular biologists study the “molecules of life”, the essential molecular components of all living organisms. We aim to understand how these molecules perform their functions, using a variety of modern molecular and biochemical approaches including structural analysis at the atomic level by X-ray crystallography, NMR spectrometry, and other biophysical methods. The knowledge gained by this research gives us opportunity to invent and develop novel ways of altering biological processes to our advantage, with applications in molecular medicine, biotechnology, synthetic biology, as well as industry.
