Document Summary
Bigass mega list of proteins and tfiih phosphorylates ser5 of ctd of rnpii and h2b during transcription elongation activate the gene or dna for transcription. Tfiid general transcription factor made up of tbp and taf. Tbp subunit of tfiid which binds to the tata box ( tata binding protein ) Taf subunit of tfiid which recognizes gre and inr (sequences near tss that are not tata) Tfiib general transcription factor, recognizes bre and allows for rna polymerase orientation. Tfiif general transcription factor, bound to rna polymerase, stabilizes tfiid and tfiib and brings in tfiie. Tfiie general transcription factor, attracts and regulates tfiih. Tfiih general transcription factor, helicase activity to open up dna helix, and kinase activity which. Swi/snf atp-dependent remodelling complex subunit; modify dna around nucleosomes to allow for sliding. Iswi atp-dependent remodelling complex subunit; slides nucleosome without altering structure. Swr atp-dependent remodelling comples subunit; switches h2a-h2b with h2a. z-h2b.
