Protein Information
Function DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest core component of RNA polymerase I which synthesizes ribosomal RNA precursors. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol I is composed of mobile elements and RPA2 is part of the core element with the central large cleft and probably a clamp element that moves to open and close the cleft (By similarity).
Cellular Location Nucleus, nucleolus

Eukaryotic RNA polymerase I (pol I) is responsible for thetranscription of ribosomal RNA (rRNA) genes and production of rRNA,the primary component of ribosomes. Pol I is a multisubunit enzymecomposed of 6 to 14 polypeptides, depending on the species. Most ofthe mass of the pol I complex derives from the 2 largest subunits,Rpa1 and Rpa2 in yeast. POLR1B is homologous to Rpa2 (Seither andGrummt, 1996 [PubMed 8921381]).
