General annotation (Comments)
| Function | Component of the transcription factor SL1/TIF-IB complex, which is involved in the assembly of the PIC (preinitiation complex) during RNA polymerase I-dependent transcription. The rate of PIC formation probably is primarily dependent on the rate of association of SL1/TIF-IB with the rDNA promoter. SL1/TIF-IB is involved in stabilization of nucleolar transcription factor 1/UBTF on rDNA. Formation of SL1/TIF-IB excludes the association of TBP with TFIID subunits. Recruits RNA polymerase I to the rRNA gene promoter via interaction with RRN3. Ref.8 Ref.9 |
| Subunit structure | Component of the transcription factor SL1/TIF-IB complex, composed of TBP and at least TAF1A, TAF1B, TAF1C and TAF1D. In the complex interacts directly with TBP, TAF1A and TAF1B. Interaction of the SL1/TIF-IB subunits with TBP excludes interaction of TBP with the transcription factor IID (TFIID) subunits. Interacts with MYC and RRN3. Interacts with p53/TP53; the interaction prevents the association of SL1/TIF-IB with UBTF and represses RNA polymerase I transcription. Ref.1 Ref.7 Ref.8 Ref.10 |
| Subcellular location | |
| Post-translational modification | Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.11 Ref.12 |
| Sequence caution | The sequence BAD92831.1 differs from that shown. Reason: Probable cloning artifact. |
