Entwicklung von chemischen Initiatoren der Dimerisierung von HaloTag und SNAP‐Tag zur Untersuchung von Signaltransduktion induziert durch Rezeptor‐Oligomerisierung

open access: yesAngewandte Chemie, EarlyView.
Die Kontrolle von Protein‐Interaktionen ist entscheidend für das Verständnis von Signaltransduktionsprozessen. Antikörperbasierte Methoden stoßen dabei an ihre Grenzen, doch chemische Dimerisierungsinduktoren (CIDs), die HaloTags und SNAP‐Tags nutzen, ermöglichen eine präzise Steuerung.
