Human Gene TAF1C (uc002fhn.3) Description and Page Index
  Description: Homo sapiens TATA box binding protein (TBP)-associated factor, RNA polymerase I, C, 110kDa (TAF1C), transcript variant 1, mRNA.
RefSeq Summary (NM_005679): Initiation of transcription by RNA polymerase I requires the formation of a complex composed of the TATA-binding protein (TBP) and three TBP-associated factors (TAFs) specific for RNA polymerase I. This complex, known as SL1, binds to the core promoter of ribosomal RNA genes to position the polymerase properly and acts as a channel for regulatory signals. This gene encodes the largest SL1-specific TAF. Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2011].

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.
PTM: Phosphorylated upon DNA damage, probably by ATM or ATR.
SEQUENCE CAUTION: Sequence=BAD92831.1; Type=Miscellaneous discrepancy; Note=Probable cloning artifact;

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.
