Plymouth Proteomics Research Group

The Plymouth Proteomics Research Group develops and applies advanced proteomic technologies to study human diseases addressing various research questions ranging from biomarker diagnostics to disease mechanisms.

Our key research areas are malaria biology, membrane proteome dynamics, and epigenetic modifications.

We are involved in various internal and external projects with our expertise. If you are interested in proteomics service or a research collaboration, please contact Dr Vikram Sharma from Plymouth University Systems Biology Centre.

Malaria biology:

The malaria proteomics research headed by Dr Edwin Lasonder focuses on studying the biology of the parasite P. falciparum in human host for the development of novel intervention strategies using a variety of methods including expression profiling, post-translational modification (PTM) studies and protein-protein interaction network analysis.

Malaria. Release of malaria parasites from red blood cell.

Membrane protease function

Membrane proteome dynamics:

Current investigations of membrane proteome dynamics headed by Dr Ansgar Poetsch include:

  • Key events and players in sperm chemo-perception. Targeted proteomics techniques shall deliver stoichiometric information about signalling proteins and posttranslational protein modifications (PTMs).
  • Elucidation and function of membrane proteolysis in microorganisms. Advanced protein turnover approaches are used to discover new targets of membrane proteases and provide additional functional insight.

These projects are conducted in collaboration with partners from UK, Germany and Argentina.
