Kim Ashley Nasmyth FRS (born 18 October 1952)[1] is the Whitley Professor of Biochemistry at the University of Oxford and a Fellow of Trinity College, Oxford.[2][3]

Career and research[edit]

Nasmyth was formerly the Director of the Research Institute of Molecular Pathology (IMP) in Vienna, Austria and former Head of the Department of Biochemistry of the University of Oxford. His research focuses on the fundamental questions of molecular biology, using Saccharomyces cerevisiae as a model organism. He is a codiscoverer of cohesin, a protein complex crucial for faithful chromosome segregation during cell division.[4] He is a member of the Advisory Council for the Campaign for Science and Engineering.[5][6][7] His research has been funded by the Medical Research Council (MRC).[8]

Awards and honours[edit]

Nasmyth was elected a Fellow of the Royal Society in 1988. His nomination reads:

Distinguished for his work on the molecular genetics of yeast. His early work made substantial contributions to the study of the cell cycle in fission yeast, including the isolation and characterisation of cell cycle mutants and the first identification of a gene product (DNA ligase) in these mutants. His main contribution has been to the understanding of the intricate sequence of transcriptional regulation which occurs during the transitions of haploid homothallic spores into diploid cells and their subsequent behaviour. His results have produced important insights into the mechanism of mating type switching by showing how mating type genes regulate the expression of other genes and how the mating type genes are themselves regulated by the transposition of silent copies away from a silencer element. He demonstrated that the pedigree of mating type switching is due to the pattern of expression in the HO endonuclease gene which initiates the mating type gene conversion and which is expressed only in mother cells at a late stage of the Gl phase of the cell cycle. He discovered and characterised a transcription factor for the HO gene called SW15, which is distributed asymmetrically at cell division, and which explains why it is that only the mother cell and not the daughter can switch its mating type. Nasmyth has also made other major contributions to molecular biology. He was one of the first to demonstrate that gene expression can be regulated through specific control elements which are distant from the start of transcription and he has recently characterised a transcription factor, which is apparently involved in both activation and repression depending upon the context of its binding site.[9]

In addition, Nasmyth has also been awarded the following:
