Tbpl1 | TATA box-binding protein-like protein 1; Part of a specialized transcription system that mediates the transcription of most ribosomal proteins through the 5'-TCT-3' motif which is a core promoter element at these genes (By similarity). Seems to also mediate the transcription of NF1. Does not bind the TATA box. (186 aa) | ||||
Taf1d | TATA box-binding protein-associated factor RNA polymerase I subunit D; 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 (By similarity). (322 aa) |
