DNA-dependent protein kinase catalytic subunit binds to the transactivation domain 1 of NF-κB p65.

ABSTRACT: Nuclear factor-kappa B (NF-κB) is a transcriptional factor that binds to the ∼10-base-pair κB motif on target genes and acts as an inflammatory regulator. Since dysregulation of NF-κB is thought to be related to various diseases, it would be very important to elucidate its post-translational modifications and binding partners in detail and to deeply understand mechanisms of the NF-κB dysregulation. NF-κB p65 is known to interact with the basic transcription factor TFIID subunit hTAF_II31/TAF9 through the ФXXФФ (Ф, hydrophobic amino acid; X, any amino acid) motif in a similar fashion to p53. MDM2 is known to inhibit p53 from binding to hTAFII31/TAF9 by masking p53's ФXXФФ motif. Here, as can be rationalized from this observation, we searched for novel nuclear protein
