Interaction with the Yes-associated protein (YAP) allows TEAD1 to positively regulate NAIP expression

Although the expression of the neuronal apoptosis inhibitory protein (NAIP) gene is considered involved in apoptosis suppression as well as in inflammatory response, the molecular basis of the NAIP gene expression is poorly understood. Here we show that the TEA domain protein 1 (TEAD1) is able to positively activate the transcription of NAIP. We further demonstrate that this regulation is mediated by the presence of the endogenous Yes associated protein (YAP) cofactor, and requires the interaction with YAP. We finally identified an intronic region of the NAIP gene responding to TEAD1/YAP activity, suggesting that regulation of NAIP by TEAD1/YAP is at the transcriptional level.
