Title
(EN) SYSTEMS FOR PROTEIN-PROTEIN INTERACTION SCREENING
(FR) SYSTÈMES DE CRIBLAGE D'INTERACTIONS PROTÉINE-PROTÉINE
Abstract
(EN)
Described herein are methods and systems useful for interrogating protein-protein interactions. These systems utilize non-functional fragments of polypeptides that can complement each other to form a fully functional fragment in vivo. The fully functional polypeptide releases a transcription regulating polypeptide that can bind and activate or repress a reporter element.
(FR)
L'invention concerne des procédés et des systèmes utiles pour analyser les interactions protéine-protéine. Ces systèmes utilisent des fragments non fonctionnels de polypeptides pouvant se compléter l'un par rapport à l'autre pour former un fragment entièrement fonctionnel in vivo. Le polypeptide entièrement fonctionnel libère un polypeptide de régulation de la transcription pouvant se lier et activer ou réprimer un élément rapporteur.
