Protein
TATA box-binding protein-associated factor RNA polymerase I subunit B
Organism
Oryza sativa subsp. indica
Function
Component of RNA polymerase I core factor complex that acts as a GTF2B/TFIIB-like factor and plays a key role in multiple steps during transcription initiation such as pre-initiation complex (PIC) assembly and postpolymerase recruitment events in polymerase I (Pol I) transcription. Binds rDNA promoters and plays a role in Pol I recruitment (By similarity).
Similarity
Belongs to the RRN7/TAF1B family.
