Secondary Information |
---|
Protein Function | Negative DNA supercoiling partially compensates for the defects of TFIIF mutants in initiation, indicating that TFIIF may help to untwist the DNA helix for initiation. |
---|
Biochemical Properties | Single amino acid substitutions at hydrophobic residues L155, W164, I176, and M177 have similar activity to RAP74(1-158). |

Additional Comments | Mutagenic analysis shows that the N-terminal region of RAP74 between L155 (leucine at codon 155) and M177 is important for initiation. Mutants in this region have reduced activity in transcription, but none are inactive. |
