For a high-level explanation you'd have to look elsewhere - with few
exceptions all of us here are simple lab rats. Intracellular
protein-protein interactions are the subject of the two-hybrid system (and
its modifications, incl. non-yeast cellular environs). Check Fields and/or
Brent for refs and reviews, if that's gonna be high enough level for you.
