YY1 (Yin Yang 1) is a transcriptional repressor protein in humans that is encoded by the YY1 gene.

YY1 is a ubiquitously distributed transcription factor belonging to the GLI-Kruppel class of zinc finger proteins. The protein is involved in repressing and activating a diverse number of promoters. Hence, the YY in the name stands for "yin-yang." YY1 may direct histone deacetylases and histone acetyltransferases to a promoter in order to activate or repress the promoter, thus implicating histone modification in the function of YY1.

YY1 has been shown to interact with:
