Caroline Dean works at the John Innes Centre (Norwich) on epigenetic regulation of developmental control genes in Arabidopsis. This depends on heritable chromatin-associated complexes that are highly conserved between animals and plants such as Polycomb Repressive Complex 2 (PRC2). Her focus has been on FLC, whose expression determines the timing of flowering after cold spells (1). She has discovered several components of this epigenetic switch by genetic screens, including the VIN/VEL proteins. These proteins form punctate nuclear structures upon overexpression in plant and animal cells, similar to the Wnt signalosomes assembled by Dishevelled through dynamic head-to-tail polymerization of its DIX domain (2). Our collaboration is aimed at the biochemical and structural analysis of VIN/VEL proteins and their domains, to test whether VIN/VEL proteins polymerise, and whether this underpins PRC2 recruitment and heritable epigenetic switching.

Gillian Griffiths is a Wellcome Trust Principal Research Fellow based at the Cambridge Institute for Medical Research. Her research is focused on understanding the cell biology of cytotoxic T lymphocytes, key cells of the immune system that destroy virally infected and cancer cells. She identified a novel role for the centrosome in directing secretion of modified secretory lysosomes and has identified many of the proteins involved in this process by studying immunodeficiencies. Recent research has taken advantage on new advances in high resolution imaging to study the remarkable polarisation that these cells undergo when they encounter their targets. She is currently collaborating with Manu Derivery to use micropatterned surfaces to follow T cell polarisation and James Manton in using Light Sheet microscopy.

Wanda Kukulski is Professor of Biochemistry at the Institute of Biochemistry and Molecular Medicine at the University of Bern, Switzerland. Her group is interested in the diversity of specialised membrane architectures that drive cellular functions. At present, their aim is to understand the molecular organisation and function of organelle contact sites, and dynamic reorganisations of mitochondrial membranes. The core approach is to visualise membrane shape and topology as well as protein assemblies associated with cellular membranes by correlative microscopy and electron cryo-tomography.
With Madeline Lancaster’s group they are working on combining correlative microscopy with cerebral organoid technology. They aim to visualise molecular architectures in neuronal tissue, which will allow specific questions on organelle membranes in neurons to be addressed.

Paul Lehner is a Wellcome Trust Principal Research Fellow and Honorary Consultant in Infectious Diseases at the CITIID Institute in the Jeffrey Cheah Biomedical Centre, Cambridge. His research focuses on the use of genetic and quantitative proteomic approaches to understand how viruses interact with and manipulate their host cells. His application of forward-genetic screens discovered the Human Silencing Hub ‘HUSH’, the critical transcriptional epigenetic repressor complex for silencing both newly integrated retroviruses and mobile endogenous retrotransposons. His collaboration with Felix Randow will take advantage of their complementary expertise to gain mechanistic insights into microbial pathogenesis using genetic and proteomic discovery platforms. They anticipate the discovery of common themes by which different pathogens exploit cellular pathways to overcome cell autonomous immunity and evade cellular recognition.

Kim Nasmyth currently holds the Whitley Chair at the Department of Biochemistry, University of Oxford and is a fellow of Trinity college. He was a PhD student in Mitchison’s lab in Edinburgh (1974-77), a post doc in Seattle Washington (1978-1980), a Robertson research fellow at Cold Spring Harbor (1980-81), and a member of staff at the MRC laboratory for molecular biology in Cambridge (1982-87) before moving to the Research Institute of Molecular Pathology (I.M.P) in Vienna, where he was a senior scientist from 1988 to 1997 and director from 1997 to 2006. His lab identified the cohesin complex that regulates the topology of eukaryotic chromosomes during interphase and holds sister chromatids together following their genesis during S phase. They also elucidated the mechanism by which cohesion is destroyed at the metaphase to anaphase transition, namely cleavage of cohesin’s kleisin subunit by separase, a thiol protease activated through ubiquitinylation of its inhibitory chaperone securin by the Anaphase-promoting complex or cyclosome. Kim’s lab has collaborated closely with that of Jan Löwe for nearly twenty years. Their analyses of cohesin’s structure have led to the notion that it holds sister DNAs together by entrapping them inside a tripartite ring formed by pairwise interactions between its Smc1, Smc3, and kleisin subunits. Their most recent work together has revealed aspects of the complex that enable it to compact DNAs through loop extrusion, in particular the ATP-dependent clamping of DNAs onto top of the Smc1/3 ATPase domains by a regulatory subunit called Scc2 (Nipbl). Kim’s work has been recognized by several awards, including the Gairdner foundation prize and the Breakthrough prize. He is a fellow of the Royal Society, a member of the Austrian Academy of Sciences, and a foreign honorary member of the American Academy of Arts and Sciences.

David Owen is a Wellcome Trust Principal Research Fellow based at the Cambridge Institute for Medical Research. In joint efforts with a number of other laboratories, his group use an integrated structure/in vitro/in vivo approach to study membrane trafficking along the endocytic system of mammalian cells. This involves trying to understand the molecular recognition processes that occur within, and allow the formation of, the protein coats of tubular vesicular carriers, which move between the cell surface, endosomes and degradative endolysosomes.
In collaboration with John Briggs’ group, the structures of minimal AP2/clathrin and retromer coats have been determined by cryo electron tomography: both systems are now being expanded to include more coat components. In collaboration with David Neuhaus’ NMR group, the regulation of both processes is being investigated using a combination of NMR, X-ray crystallography and high-resolution live cell imaging.

Since 2013, John Walker has been Director Emeritus at the MRC Mitochondrial Biology Unit in Cambridge. In 1994, his work, started in 1981 in the LMB’s PNAC Division and continued throughout the intervening period, on characterizing the ATP synthase in the mitochondria (and also in chloroplasts and bacteria), led to the realisation that the energy released by the oxidation of dietary sugars and fats is coupled by a mechanical rotary mechanism to generate the 60 kg of ATP that each of us makes daily to sustain our lives. This work led to the award of the Nobel Prize in Chemistry in 1997. In the 1990s, he also defined the protein composition of another huge molecular assembly in mitochondria, known as complex I, and the localisation of the 44 constituent proteins within the complex. Complex I is a key component in the respiratory chain of enzymes that converts energy from food into a transmembrane proton motive force (pmf). This work provided essential foundations for more recent investigations by colleagues into its structure and function.
Since leaving the LMB in 1998, he has continued to delve deeper into the mechanism of the ATP synthase, and especially into the question of how rotation is generated from the pmf. His recent description in 2021 (with T. Spikes and M. Montgomery) of the structure of the complete dimeric mitochondrial ATP synthase provides crucial evidence that rotation is generated by the direct application of the pmf (predominantly a voltage) to the membrane domain of the enzyme’s rotor via a Grotthus water chain. John uses his knowledge on energy conversion for medical benefit, in 2021 establishing the structure of the mycobacterial ATP synthase as a target for developing new drugs against tuberculosis.
John is a Fellow of the Royal Society, and in 2012, he was awarded its Copley Medal. He is also a Fellow of the Academy of Medical Sciences, a Fellow of Sidney Sussex College, Cambridge, an Honorary Fellow of St Catherine’s College, Oxford, a Foreign Member of L’Accademia Nazionale dei Lincei, of the Royal Netherlands Academy of Arts and Sciences, and of The Royal Society of New Zealand, and a Foreign Associate of the US National Academy of Sciences.
