The N-terminal domain of the TFIIH basal transcription factor complex p62 subunit (BTF2-p62) forms an interaction with the 3' endonuclease XPG, which is essential for activity. The 3' endonuclease XPG is a major component of the nucleotide excision repair machinery. The structure of the N-terminal domain reveals that it adopts a pleckstrin homology (PH) fold [1,2]. This PH-type domain has been shown to bind to a mono-phosphorylated inositide [2].	Domain

This domain is found in viruses, and is about 30 amino acids in length. It is found in association with Pfam:PF02232. This domain is the C terminal of the HSV virion protein 16. This protein is a transcription promoter. The C terminal domain is the carboxyl subdomain of the acidic transcriptional activation domain. The protein binds to DNA binding proteins to carry out its function. Such proteins include TATA binding protein, CBP, TBP-binding protein, etc.	Domain
