Research projects


Ubiquitin signals in Parkinson’s disease


Ubiquitin signalling controls almost every cellular process in humans, including targeting poorly folded proteins for destruction to prevent them harming the cell. When ubiquitin signalling goes wrong, many different disease states can occur, including neurodegenerative disorders such as Parkinsons Disease (PD).

One gene associated with PD is parkin, which gives rise to an enzyme responsible for tagging many different proteins with ubiquitin. The aims of this project are to understand on a biochemical and molecular level how parkin targets a specific substrate, Miro1, and how the ubiquitin signals applied to Miro1 are edited & interpreted.

This project will involve expressing and purifying multiprotein complexes, and developing protocols for generating the ubiquitin signals, and enzymatic assays for the regulation of these signals.

Mitochondria biogenesis and stress responses in health and disease


Maintenance of functional mitochondria is essential for life and an important therapeutic target in several diseases, including age-related neurodegenerative diseases. Mitochondrial dysfunction is linked to redox damage and dysregulation of mitochondrial protein homeostasis mechanisms. The burden of these to mitochondria can often lead to cell death. Mechanisms that control import of proteins and elimination of damaged proteins, redox regulation and protein homeostasis are therefore critical for safeguarding mitochondria under stress conditions and key to cell physiology. Despite their importance, these mechanisms remain elusive.

Our recent work has revealed that under stress conditions a number of proteins, many of them with critical antioxidant and chaperone functions, are targeted to mitochondria (particularly in the intermembrane space) via unconventional pathways. Once inside the mitochondria, these proteins protect the organelles from oxidative damage and protein aggregation, which pose a dual threat to cell homeostasis. It is critical to understand the key players and how they are imported to mitochondria to exert a pro-survival function, how they affect the function of critical proteins like the inner membrane metabolite transporters that are critical for metabolism and how they inhibit the onset of diseases like neurodegeneration.

Recent evidence from our lab has identified several proteins that undergo stress-dependent targeting to mitochondria where they either assist the physiological mitochondria biogenesis process or facilitate the elimination of damaged proteins by proteolytic systems like the proteasome. The project will therefore address how stress-responsive alterations of mitochondria biogenesis ensure mitochondria fitness and metabolic rewiring as a protection against irreversible damage.


Our overarching goal is to determine a previously hidden aspect of cells undergoing oxidative stress whereby their capacity to target proteins to mitochondria is substantially altered to benefit the cell (for example through control of mitochondrial Reactive Oxygen Species). The broader effects on function of resident mitochondrial transporters is also key to understand as a mechanism of stress-induced metabolic rewiring.

This will be achieved by three specific aims to be addressed in this project:

  1. To characterize new mitochondrial targeting mechanisms of proteins that become alternatively translated under oxidative stress
  2. To elucidate specific stress-induced modifications on the mitochondrial protein import components and inner membrane metabolite transporters that underpin their expanded transport capacity under stress
  3. To explore how misfolded and aggregated mitochondrial proteins are exported for clearance by the proteasome as a means to maintain a healthy protein balance within mitochondria and influence cell death pathways.

Training outcomes:

The student will be trained in several complementary biological disciplines in the laboratories of the supervisory team:

  1. Molecular biology and genetics approaches will be used to generate several yeast (S. cerevisiae) models for the project. Further, shRNA and CRISPR/Cas-9 approaches will be used for gene manipulations in mammalian cells (fibroblasts and cancer cell lines).
  2. Biochemistry and Cell Biology techniques will be employed to assess protein import, protein-protein interactions, intramitochondrial localization using FRET, split GFP and super-resolution microscopy and mitochondrial function using high-resolution respirometry
  3. Biophysical and structural biology assays will be applied for purified proteins in a reconstituted system using microscale thermophoresis and isothermal titration calorimetry for measuring binding affinities between proteins and NMR for structural analysis
  4. Bioinformatic and proteomics approaches will assist the student to elucidate unknown mitochondrial targeting motifs and identify redox-related PTMs on protein translocon components. Omics approaches will be performed in collaboration with experts (Redox modifications group at the National Proteome Facility, Beijing, China) and professional services. The student will learn to prepare the samples (including experimental design) for analysis as well as to analyse and interpret the results.
  5. Transferable skills (eg. communication, networking, time management) will be provided by the MVLS Researcher Development Plan and by tailor-made activities within the participating labs which are very active in KE activities (public engagement, Industry liaison events) and extended interactions with the EMBO, FEBS and international mitochondria research community.

Exploring the structure and function of protein complexes by high-resolution cryo-EM

Outline & aim

Highly specialised protein complexes are critical regulators of cell division and homeostasis. The full understanding of the functional mechanisms of such complexes requires an in-depth knowledge of their structural organisation, which we study primarily by high resolution cryo-electron microscopy (cryo-EM) and single particle analysis. By resolving protein complexes in different functional states, representing snapshots of the complex in action, we aim at gaining detailed knowledge of their functional and regulatory mechanisms.

We also aim at obtaining information to guide on how to specifically target those complexes for therapeutic use. The structural data obtained is combined with further biochemical and biophysical information for a full functional characterisation.


Our work focuses on high-resolution cryo-EM and single particle analysis, together with protein purification and biochemical/biophysical characterisation.

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.

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.

PhD programmes in biochemistry and biotechnology will carry out a cutting-edge research project in an area that aligns with the expertise of one or more of our principal investigators in the fields of biochemistry and biotechnology. The subject of the project may be fundamental “blue skies” science or may be targeted at an important application. Projects may also be related to basic science and integrate with our existing research themes, while other projects are more focused on translational aspects of our research.

Some of our current research areas are:

  • cell signalling mechanisms in mammals, plants and insects
  • mitochondrial biogenesis and mitochondrial proteins
  • mechanisms of DNA sequence rearrangements
  • DNA sequences in human disease
  • genetic circuits and switches for synthetic biology
  • plant molecular biology
  • photosynthesis, plant photobiology, circadian factors in plants
  • structural determination by NMR and X-ray crystallography
  • structural bioinformatics, molecular modelling
  • drug receptors, molecular pharmacology
  • nuclear genomic architecture
  • mechanisms of intracellular trafficking
  • protein folding, targeting and modification
  • protein-protein and protein-DNA interactions
  • cell-surface interactions
