FRET

An interaction is inferred when close proximity of interaction partners is detected by fluorescence resonance energy transfer between pairs of fluorophore-labeled molecules, such as occurs between CFP (donor) and YFP (acceptor) fusion proteins.

Gialpha and Gbeta subunits both define selectivity of G protein activation by alpha2-adrenergic receptors.

Gibson SK, Gilman AG

Previous studies of the specificity of receptor interactions with G protein subunits in living cells have relied on measurements of second messengers or other downstream responses. We have examined the selectivity of interactions between alpha2-adrenergic receptors (alpha2R) and various combinations of Gialpha and Gbeta subunit isoforms by measuring changes in FRET between Gialpha-yellow fluorescent protein and cyan fluorescent protein-Gbeta chimeras ...

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.
