Crystal structures of the recombinant β-factor XIIa protease with bound Thr-Arg and Pro-Arg substrate mimetics (2019)
Journal Article
Pathak, M., Manna, R., Li, C., Kaira, B. G., Hamad, B. K., Belviso, B. D., …Emsley, J. (2019). Crystal structures of the recombinant β-factor XIIa protease with bound Thr-Arg and Pro-Arg substrate mimetics. Acta Crystallographica. Section d, Structural Biology, 75(6), 578-591. https://doi.org/10.1107/s2059798319006910

© 2019 International Union of Crystallography. Coagulation factor XII (FXII) is a key initiator of the contact pathway, which contributes to inflammatory pathways. FXII circulates as a zymogen, which when auto-activated forms factor XIIa (FXIIa). Her...

Plasma kallikrein structure reveals apple domain disc rotated conformation compared to factor XI (2019)
Journal Article
Li, C., Voos, K. M., Pathak, M., Hall, G., McCrae, K. R., Dreveny, I., …Emsley, J. (2019). Plasma kallikrein structure reveals apple domain disc rotated conformation compared to factor XI. Journal of Thrombosis and Haemostasis, 17(5), 759-770. https://doi.org/10.1111/jth.14418

Background Plasma prekallikrein (PK) and factor XI (FXI) are apple domain‐containing serine proteases that when activated to PKa and FXIa cleave substrates kininogen, factor XII, and factor IX, respectively, directing plasma coagulation, bradykinin...

Expression of human ficolin-2 in hepatocytes confers resistance to infection by diverse hepatotropic viruses (2019)
Journal Article
Irving, W. L., Jalal, P. J., Urbanowicz, R. A., Horncastle, E., Pathak, M., Goddard, C., …Tarr, A. W. (2019). Expression of human ficolin-2 in hepatocytes confers resistance to infection by diverse hepatotropic viruses. Journal of Medical Microbiology, 68(4), 642-648. https://doi.org/10.1099/jmm.0.000935

The liver-expressed pattern recognition receptors (PRRs) mannose binding lectin (MBL), ficolin-2 and ficolin-3 contribute to the innate immune response by activating complement. Binding of soluble ficolin-2 to viral pathogens can directly neutralize...

Coagulation factor XII protease domain crystal structure (2015)
Journal Article
Pathak, M., Wilmann, P., Awford, J., Li, C., Hamad, B., Fischer, P., …Emsley, J. (2015). Coagulation factor XII protease domain crystal structure. Journal of Thrombosis and Haemostasis, 13(4), 580-591. https://doi.org/10.1111/jth.12849

Background: Coagulation factor XII is a serine protease that is important for kinin generation and blood coagulation, cleaving the substrates plasma kallikrein and FXI. Objective: To investigate FXII zymogen activation and substrate recognition by d... Read More about Coagulation factor XII protease domain crystal structure.
