CC -!- FUNCTION: Component of RNA polymerase I core factor complex that acts
CC as a GTF2B/TFIIB-like factor and plays a key role in multiple steps
CC during transcription initiation such as pre-initiation complex (PIC)
CC assembly and postpolymerase recruitment events in polymerase I (Pol I)
CC transcription. Binds rDNA promoters and plays a role in Pol I
CC recruitment (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleolus {ECO:0000250}.
CC -!- DOMAIN: Although it shares weak sequence similarity with GTF2B/TFIIB,
CC displays a similar subdomain organization as GTF2B/TFIIB, with a N-
CC terminal zinc finger, a connecting region (composed of B-reader and B-
CC linker regions), followed by 2 cyclin folds. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the RRN7/TAF1B family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAV43874.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=EEE63371.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
