Intramembrane serine proteases of the rhomboid family are widespread, and their gradually uncovered functions in different organisms already suggest medical relevance for infectious diseases and cancer. However, selective inhibitors that could serve as research tools for rhomboids, for validation of their disease relevance, or as templates for drug development are lacking. Here I summarize the current knowledge about rhomboid protease mechanism and specificity, overview the currently used inhibitors, and conclude by proposing avenues for future development of rhomboid protease inhibitors.
Keywords: Disease; Inhibitor; Mechanism; Rhomboid protease; Substrate specificity.
