Our lab is interested in how genetic material is packaged in eukaryotes and the implications this has for biological processes. Within each cell of our body, we have nearly four metres of DNA distributed over 46 chromosomes which is sequestered in a nucleus of only 1000 m3.
Chromatin must, therefore, fulfil two conflicting roles: structure DNA so that genomic instability is minimised, but at the same time remain accessible to factors involved in transcription, replication and repair. In studying these contrary roles, our investigations span two length scales, namely the assembly of individual nucleosomes to form the 10 nm fibre and the mechanics of higher-order chromatin domains. To do this we utilise both in vitro biochemical approaches and advanced live-cell imaging.

Mike and Andrew develop a real-time pulse chase strategy called 'RAPID-release' to probe the histone chaperoning pathway & propose a pathway for the import of monomeric histones.

I read biochemistry at Leicester before moving to the University of Dundee to do my PhD under Tom Owen-Hughes. My PhD was focused predominantly on using pulsed EPR to probe the structure of the H3-H4 tetramer complex in solution. After my PhD I continued in the chromatin field carrying out a postdoc at the LMU in Munich in the lab of Andreas Ladurner. There I investigated the role of TPR proteins in histone chaperoning, revealing a novel histone peptide binding module in the protein NASP (Bowman et al., 2016), and discovered a minimal two-chaperone system for the efficient folding of an H3-H4 dimer in vitro (Bowman et al., 2017).
Following my postdoc I took up a position as an Independent Research Fellow at the University of Warwick as part of the Warwick-Wellcome Quantitative Biomedicine Program. During this time I became interested in using a broader range of tools to study the dynamics of the histone chaperoning network. Combining a novel synthetic pulse-labelling technique (RAPID-release) with microscopy and more traditional biochemical tools, we proposed that histones H3 & H4 are rapidly imported into the nucleus as monomers, not as dimeric units, and that a stable nuclear pool of monomeric H3 exists bound to NASP (Apta-Smith et al., 2018).
Currently I am a Sir Henry Dale Fellow.
