My research focuses on investigating the complex biological processes of blood hemostasis and thrombosis with a special interest in the co-operation of different blood cell types and plasma proteins with a focus on molecular structure. . A major focus in recent years is the structure of plasma proteases to elucidate the mechanism of latency, substrate recognition, selectivity, co-factor/membrane lipid interactions and inhibitor design. JE group has published the first crystal structure of coagulation factor XI protease in complex with a peptide from the co-factor HK (Blood 2016) which shows the enzyme in a latent conformation. JE group has recently solved the first example of structure in an active conformation of the related apple domain containing protease prekallikrein (JTH 2019-front cover, Blood 2020) which revealed a major 180 degree rotational conformational change termed apple domain disc rotation. We have also determined prekallikrein-substrate complex crystal structures (manuscript drafted). Also my group reported the first crystal structure of the Factor XII (FXII) protease (JTH 2015) which revealed a latent conformation and more recently the active form in complex with peptidomimetic inhibitor (Acta Cryst in press 2019). I was involved in modelling the partially latent structure of the single chain FXII active site (Blood 2017). Recent structures include the complement receptor-FXII complex (manuscript in revision Blood 2020. I have advanced understanding of the field of cell receptor structural biology for ~25 years and contributed to greater understanding of the molecular basis of cell receptor ligand interactions for both extracellular domains forming connections to the extracellular matrix [1,10] and intracellular domains which form connections to the cytoskeleton (PMID: 15642262, PMID: 15272303, PMID: 16135522, PMID: 16407302).
