Protein kinases regulate vital processes like differentiation, proliferation, adaptation and motility in all cells. The human parasite Leishmania like other eukaryotes relies on signal transduction via reversible phosphorylation. As such parasite protein kinases are potential drug targets to be used to treat leishmaniasis, a human disease, which dependent on the parasite species and the immunological background of the host can be fatal. The project is comprised of a variety of different methods including CRISPR-Cas9, molecular biology, protein biochemistry, cell biology and screening. Genes will be cloned using modern cloning technologies. Recombinant proteins will be expressed using bacterial expression systems followed by purification and enzyme assays. Interactions of protein kinases with their interaction partners will be analysed in vivo using genetically modified parasites for proximity labelling (BioID) and mass spectrometry.
