WebHowever, LEF1 and TCF4 isoforms lacking the C1.1 domain do not form productive transcription factor complexes at theCdx1 promoter. ... This shows that the LEF1-T4C chimera must be able to bind to theCdx1 promoter in order to activate and rules out the possibility that LEF1-T4C stimulates the reporter only indirectly. WebMar 29, 2024 · A good correlation is, rather, found with binding of immunopurified holo-TFIID to this element. TFIID interacts both with Ea TATA-like and Inr sequences, but only the latter is functionally relevant. Unlike TBP, TFIID binds in the absence of TFIIA, indicating a stabilizing role for TBP-associated factors in Ea promoter recognition.
