Protein
DNA-directed RNA polymerase I subunit RPA49
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
DNA-dependent RNA polymerases catalyze the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase I (Pol I) which synthesizes ribosomal RNA precursors. Besides, RNA polymerase I has intrinsic RNA cleavage activity. The heterodimer formed by RPA34 and RPA49 stimulates transcript elongation by Pol I. Subunit RPA49 can bind both single-stranded and double-stranded DNA.
Similarity
Belongs to the eukaryotic RPA49/POLR1E RNA polymerase subunit family.
