Research Priorities: physical chemistry of molecular organisation, cell compartmentalisation, biomolecular condensates, phase separation
Anthony Hyman is a British cell biologist. He studies how the separation between different physical phases (phase separation) influences the formation of membrane-less subdivisions (compartments) within cells. He aims to understand the underlying mechanisms, the macromolecules involved and the errors that occur in the process. This knowledge can help to better understand neurodegenerative diseases and improve the development of drugs as well as the effectiveness of therapies.
Anthony Hyman's most significant achievements include functional genome research on embryos of the nematode C. elegans. He was one of the first to observe how cells use phase separation to form transient, membrane-less compartments within living cells. Many processes within a cell are organised using compartments. Usually they are surrounded by lipid membranes. In recent years, phase separation has been discovered as a new form of cellular organisation. In this process, a substance passes from one physical state (solid, liquid, gaseous) to another. In living organisms, liquid-liquid phase separation is particularly relevant. A solution of molecules segregates into two separate phases and forms liquid-filled droplets.
Anthony Hyman's research group investigates what role such dynamic, biomolecular condensates play in the transient accumulation of proteins within membrane-less compartments. This organisation (compartmentalisation) of proteins affects their function and influences biochemical processes within the cell. Molecular and cell biological methods help to understand how compartmentalisation influences molecular interactions and how it affects protein concentration and thus the microenvironment. Anthony Hyman also explores how condensates stabilise biochemical processes and achieve sensitivity to stimuli. Temperature, pH, external stimuli, protein mutations, post-translational modifications and the presence of nucleotides are possible factors that influence the formation and dissolution of condensates.
Anthony Hyman's research aims to understand how disruption of condensation can lead to the development of diseases. The goal is to understand the causes of protein-based pathologies to be able to restore physiological conditions and enable healing.
