Proteomic screening for redox state dependent protein-protein interactions

摘要

This invention provides a modified yeast two-hybrid system in order to identify NO-dependent protein-protein interactions. Bait proteins implicated in apoptotic signaling pathways were used to identify NO-dependent interactions. The physiological relevance of these interactions is demonstrated by their occurrence and dependence on endogenous NO in mammalian cells, and by the functional interrelatedness of bait and prey.
