Eukaryotic RNA polymerase 18S+ 30 proteins= 40S

Initiation of rDNA transcription Two transcription factors, UBF and SL1, bind cooperatively to the rDNA promoter and recruit RNA polymerase I to form an initiation complex. One subunit of SL1 is the TATA-binding protein (TBP) and the other is TBP- associated Factor (TAF).
