ID:TAF1C_HUMAN DESCRIPTION: RecName: Full=TATA box-binding protein-associated factor RNA polymerase I subunit C; AltName: Full=RNA polymerase I-specific TBP-associated factor 110 kDa; Short=TAFI110; AltName: Full=TATA box-binding protein-associated factor 1C; Short=TBP-associated factor 1C; AltName: Full=Transcription initiation factor SL1/TIF-IB subunit C; 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. SUBUNIT: 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. SUBCELLULAR LOCATION: Nucleus. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. SEQUENCE CAUTION: Sequence=BAD92831.1; Type=Miscellaneous discrepancy; Note=Probable cloning artifact; WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/taf1c/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
