Putting Malaria on the SHELPH
Mar 07 2013
Experts have disabled a unique member of the signalling proteins which are essential for the development of the malaria parasite. They have produced a mutant lacking the ancient bacterial Shewanella-like protein phosphatase known as SHLP1 (pronounced shelph). This mutant is unable to complete its complex life cycle and is arrested in its development in the mosquito. The discovery could help in the design of new drugs to arrest the spread of this killer disease.
SHLP1 is critical to the cellular development of the malaria parasite. It can be found at every stage in the lifecycle of the malaria parasite and for the first time experts led by The University of Nottingham have analysed their biological function.
Dr Rita Tewari and her team in the Centre for Genetics and Genomics in the School of Biology have spent three years studying the phosphatase proteins that are important building blocks in the life cycle of the malaria parasite. The findings of their latest study are published today, 21 February 2013, in the academic journal Cell Reports.
Dr Tewari said: “SHLP1 is absent in humans and can be explored as an excellent target for malaria transmission control. Prevention of malaria transmission to and from the mosquito is vital in order to stop the devastating spread of malaria. Targeting SHLP1 could be an important step to achieve this goal.”
Funded by the MRC and the Wellcome Trust, the research brought together expertise from Imperial College London, University of Oxford, the MRC National Institute for Medical Research and the University of Edinburgh.
