TADA3L: Lysates

Many DNA-binding transcriptional activator proteins enhance the initiation rate of RNA polymerase II-mediated genetranscription by interacting functionally with the general transcription machinery bound at the basal promoter.Adaptor proteins are usually required for this activation, possibly to acetylate and destabilize nucleosomes, therebyrelieving chromatin constraints at the promoter. The protein encoded by this gene is a transcriptional activatoradaptor and has been found to be part of the PCAF histone acetylase complex. In addition, it associates with the tumorsuppressor protein p53 and is required for full activity of p53 and p53-mediated apoptosis. At least fouralternatively spliced variants have been found for this gene, but the full-length nature of some variants has not beendetermined. (provided by RefSeq)
