  1. Data show that TFIIF has an important role in stabilizing TFIIB within the PIC and after transcription initiates.
    Title: Transcription factor TFIIF is not required for initiation by RNA polymerase II, but it is essential to stabilize transcription factor TFIIB in early elongation complexes.
  2. NMR and thermodynamic studies further elucidate the complex molecular mechanism by which TFIIF and FCP1 cooperate for RNAPII recycling.
    Title: NMR structure of a complex formed by the carboxyl-terminal domain of human RAP74 and a phosphorylated peptide from the central domain of the FCP1 phosphatase.
  3. Results pinpoint critical residues for RNA polymerase II subunit 5 binding to RAP30 and/or to HBx, and identify these residues in both mammalian cells and in an in vitro binding assay.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
