YAPはDNAと直接結合せず転写因子のcoactivatorとして働きます。

As YAP and TAZ are transcriptional co-activators, they do not have DNA-binding domains. Instead, when inside the nucleus, they regulate gene expression through TEAD1-4 which are sequence-specific transcription factors that mediate the main transcriptional output of the Hippo pathway.The YAP/TAZ and TEAD interaction competitively inhibits and actively dissociates the TEAD/VGLL4 interaction which functions as a transcriptional repressor.
