Professor Christian D. Doerig

Monash University


Head of the Department of Microbiology



Christian Doerig obtained his PhD in molecular virology at the Swiss Institute for Experimental Cancer Research (ISREC) in Lausanne, Switzerland. After a post-doctoral training on herpes simplex virus in the USA, he turned his attention to malaria and pioneered the study of protein phosphorylation in Plasmodium falciparum, the most virulent of the parasites causing human malaria. He is "Directeur de Recherches" at the French biomedical research agency Inserm (Institut National de la Santé et de la Recherche Médicale) and Honorary Professor of the University of Glasgow, Scotland, UK. He established the first Inserm units in the UK, at the Wellcome Trust Centre for Molecular Parasitology, University of Glasgow, and subsequently in Switzerland at the Inserm-EPFL joint laboratory, Ecole Polytechnique Fédérale de Lausanne (EPFL). In 2011, he joined Monash University in Melbourne, Australia, as Head of the Department of Microbiology, where he pursues his research on kinomics, cell proliferation and development of malaria parasites.

P. falciparum possesses 65 sequences conforming to the “eukaryotic protein kinase” (ePK) signature (to be compared to ~500 in the human kinome), many of which do not have orthologues in the mammalian kinome (Ward, P., et al., BMC Genomics, 2004. 5:79). Systematic reverse genetics has determined that about half the P. falciparum ePKs are required for asexual proliferation in erythrocytes (Solyakov, L., et al., Nature Communications, 2011, 2:565).  To elucidate the function of these enzymes in parasite development, we are implementing imaging, interactomics and comparative phosphoproteomic approaches.  This allowed us to assign functions of selected kinases in processes such as chromatin assembly (Dastidar, E.G., et al., BMC Biol, 2012. 10:5), mRNA splicing, proliferation rate (Dorin-Semblat, D., et al.. Kinome, 2013. 1:4-16) and nuclear division (Reininger, L., et al., Mol. Microbiol., 2011. 79: 205-21), and to establish that the parasite uses kinase cascades, based on phosphorylation of the kinase activation loop, including on tyrosine residues (Solyakov, L., et al., Nature Communications, 2011, 2:565).

We have shown that infection with P. falciparum hyper-activates a signalling pathway involving p21-activated kinase (PAK) and MAP/ERK kinase (MEK1) of the host erythrocyte, and that this is required for parasite survival (Sicard, A., et al., Cell. Microbiol, 2011. 13:836-45).  This suggests that inhibitors of human kinases developed in the context of cancer chemotherapy could be repositioned as potential antimalarials.
