CC -!- FUNCTION: Component of RNA polymerase I (Pol I), a DNA-dependent RNA
CC polymerase which synthesizes ribosomal RNA precursors using the four
CC ribonucleoside triphosphates as substrates. Through its association
CC with RRN3/TIF-IA may be involved in recruitment of Pol I to rDNA
CC promoters. {ECO:0000250|UniProtKB:Q3B726}.
CC -!- SUBUNIT: Component of the RNA polymerase I (Pol I) complex consisting
CC of 13 subunits: a ten-subunit catalytic core composed of POLR1A/RPA1,
CC POLR1B/RPA2, POLR1C/RPAC1, POLR1D/RPAC2, POLR1H/RPA12, POLR2E/RPABC1,
CC POLR2F/RPABC2, POLR2H/RPABC3, POLR2K/RPABC4 and POLR2L/RPABC5; a mobile
CC stalk subunit POLR1F/RPA43 protruding from the core and additional
CC subunits homologous to general transcription factors POLR1E/RPA49 and
CC POLR1G/RPA34 (By similarity). Interacts with RRN3/TIF-IA. Interacts
CC with RRN3/TIF-IA. {ECO:0000250, ECO:0000250|UniProtKB:Q3B726,
CC ECO:0000269|PubMed:12393749}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleolus
CC {ECO:0000250|UniProtKB:Q3B726}.
CC -!- TISSUE SPECIFICITY: Widely expressed. {ECO:0000269|PubMed:12438708}.
CC -!- SIMILARITY: Belongs to the eukaryotic RPA43 RNA polymerase subunit
CC family. {ECO:0000305}.
