Decision-making modules in protein interaction networks. This project aims to discover how cells use proteins to make decisions. This is important for all living things, which must react to stimuli to grow, adapt, defend themselves and to die. The project’s anticipated outcome is the systems-level identification of decision-making modules in an intracellular network. Its focus is on the smallest possible modules, which contain a decision-making protein with two modifications that control protein ....Decision-making modules in protein interaction networks. This project aims to discover how cells use proteins to make decisions. This is important for all living things, which must react to stimuli to grow, adapt, defend themselves and to die. The project’s anticipated outcome is the systems-level identification of decision-making modules in an intracellular network. Its focus is on the smallest possible modules, which contain a decision-making protein with two modifications that control protein-proteins interactions. It will investigate two recurrent decision-making modules. The expected benefits of the project include new means to decipher biological complexity, and targets to modulate biosystems by genome editing or with drugs.Read moreRead less
The role and regulation of protein methylation: a study using the recently developed methylation network of yeast. Tiny changes to proteins, such as methylation, can alter the way they interact with other proteins. This project will investigate the dynamics of protein methylation during the life of the yeast cell. The project results will be of long term relevance to situations where we may want to stop cells dividing, such as cancer or infectious disease.
The effect of methylation and phosphorylation on ribosome function. This project aims to discover how cells regulate ribosome function and selectivity, by modifying their ribosomal proteins. This affects protein synthesis, a process which is central to the growth of all living things. Expected outcomes include new knowledge on the regulation of protein synthesis, improved techniques for the study of this process and an enhanced capacity for international collaboration. New avenues for the artifi ....The effect of methylation and phosphorylation on ribosome function.

This affects protein synthesis, a process which is central to the growth of all living things. Expected outcomes include new knowledge on the regulation of protein synthesis, improved techniques for the study of this process and an enhanced capacity for international collaboration. New avenues for the artificial regulation of the ribosome may also emerge, relevant to synthetic biology and the engineering of industrial yeasts. The project should provide significant new findings for the research community, generate research citations and contribute to a highly skilled workforce by the training of staff and students.Read moreRead less
Does phosphorylation regulate the methylation of proteins? . The interaction of proteins is a fundamental requirement of life. Tiny switches on proteins affect how they interact but little is known about how these are controlled. This project will study the complex interplay between two types of switches; one is expected to control the other. This will provide new insights into how the cell functions.
The Regulatory Network of Histone Methylating and Demethylating Enzymes. This project aims to discover how cells regulate histone methylation enzymes. This process ultimately affects which genes can be turned on or off inside cells; something which is central to growth and development in all animals, all plants and some microbes. Expected outcomes include new knowledge on the regulation of histone methylation, improved techniques for the study of this process and enhanced capacity for internatio ....The Regulatory Network of Histone Methylating and Demethylating Enzymes.

The structure in four-dimensions of a mammalian nuclear body. The project aims to develop a working model of a micron-sized molecular machine implicated in numerous aspects of gene regulation. Bodies in the mammalian cell nucleus are larger than macromolecular complexes and smaller than organelles. Recent developments in structural, molecular and cell biology are allowing us to begin to interpret their structure-function relationships. This project capitalises on a wealth of structural and funct ....The structure in four-dimensions of a mammalian nuclear body. The project aims to develop a working model of a micron-sized molecular machine implicated in numerous aspects of gene regulation. Bodies in the mammalian cell nucleus are larger than macromolecular complexes and smaller than organelles. Recent developments in structural, molecular and cell biology are allowing us to begin to interpret their structure-function relationships. This project capitalises on a wealth of structural and functional data on nuclear bodies termed paraspeckles with the aim of developing a structural model. It aims to track tens of proteins and long non-coding RNA from paraspeckles as they proceed through the cell cycle, by combining genome engineering, super-resolution microscopy, proteomics and in vitro interaction studies.Read moreRead less
Mechanisms of gene regulation. This project aims to determine the molecular basis of specific gene targeting. Transcription factor complexes regulate gene expression by binding to DNA at specific sites, modifying and looping chromatin, and recruiting the basal transcription machinery. Using blood cell transcription factor complexes as a model, this project will reveal interactions between sets of proteins that fine-tune DNA binding and recruit accessory proteins that regulate gene expression. Th ....Mechanisms of gene regulation. This project aims to determine the molecular basis of specific gene targeting. Transcription factor complexes regulate gene expression by binding to DNA at specific sites, modifying and looping chromatin, and recruiting the basal transcription machinery. Using blood cell transcription factor complexes as a model, this project will reveal interactions between sets of proteins that fine-tune DNA binding and recruit accessory proteins that regulate gene expression. The mechanistic detail provided is expected to inform the artificial up- or down-regulation of genes in biotechnological applications and ultimately treat disease which have a genetic component.Read moreRead less
