Category:ECO:0000025 ! hybrid interaction evidence

name: hybrid interaction evidence
def: "A type of affinity evidence where proteins of interest (bait and prey) are covalently linked to incomplete fragments of a third protein (reporter) and expressed in vivo, at which time interaction between bait and prey proteins brings reporter fragments in close enough proximity to allow them to reform and become a functional reporter protein." [ECO:MCC, PSI-MI:MI\:0090]

is_a: ECO:0000023 ! affinity evidence
comment: Typically enzymes which confer resistance to antibiotics, such as Dihydrofolate reductase or Beta-lactamase, or proteins that give colorimetric or fluorescent signals are used. The Bait protein is generally the protein under study and the methods are readily adaptable to highthroughput mode.
