The presence of secretion systems by which the so-called ‘effector-proteins’ can be injected into the host’s cytosol to interact with host proteins and modulate molecular pathways is a unique feature of proteobacteria.

We analyze the protein-protein interaction network of effector proteins from (commensal) microbes with the host interactome to understand which processes and disease modules are targeted by this underexplored molecular mechanism. We identify effectors and secretion systems in microbial reference genomes and meta-genome datasets.
