DNA-directed RNA polymerases I and III subunit RPAC2 (Polr1d)

DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Common core component of RNA polymerases I and III which synthesize ribosomal RNA precursors and little RNAs, such as 5S rRNA and tRNAs, respectively.
