Transcription factor 7-like 2 (TCF7L2)

Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter at a sequence-specific manner. Acts as repressor in the absence of CTNNB1, and as activator in its presence.

Activates transcription from promoters with several copies of the Tcf motif 5'-CCTTTGATC-3' in the existence of CTNNB1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7L2/TCF4 and CTNNB1.
