FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Eukaryotic RNA polymerase I (pol I) is responsible for the transcription of ribosomal RNA (rRNA) genes and production of rRNA, the primary component of ribosomes. Pol I is a multisubunit enzyme composed of 6 to 14 polypeptides, depending on the species. Most of the mass of the pol I complex derives from the 2 largest subunits, Rpa1 and Rpa2 in yeast. POLR1B is homologous to Rpa2 (Seither and Grummt, 1996 [PubMed 8921381]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Mice homozygous for a gene trapped allele exhibit embryonic lethality prior to implantation. [provided by MGI curators]
