What's a GeneRIF?

Tfg2 C-terminal domain interacts with double-stranded DNA oligonucleotides.
Title: Structural and binding studies of the C-terminal domains of yeast TFIIF subunits Tfg1 and Tfg2.
Tfg2p is retained in the nucleus through DNA binding in Saccharomyces cerevisiae.
Title: Kap104p imports the PY-NLS-containing transcription factor Tfg2p into the nucleus.
We show that Anc1 is required for growth on galactose as the sole carbon source, and that it is recruited to the UAS of the GAL1 gene after induction.
Title: Anc1 interacts with the catalytic subunits of the general transcription factors TFIID and TFIIF, the chromatin remodeling complexes RSC and INO80, and the histone acetyltransferase complex NuA3.
Evidence that the Tfg1/Tfg2 dimer interface of TFIIF is located in proximity to the B-finger of TFIIB near the active center of RNA polymerase II (RNAP II) where the TFIIB-TFIIF-RNAP II interface plays a key role in transcription start site selection.
Title: Evidence that the Tfg1/Tfg2 dimer interface of TFIIF lies near the active center of the RNA polymerase II initiation complex.
