GeneCards Summary for POLR1A Gene

POLR1A (Polymerase (RNA) I Polypeptide A, 194kDa) is a Protein Coding gene. Diseases associated with POLR1A include acrofacial dysostosis, cincinnati type and kidney hypertrophy. Among its related pathways are GPCR Pathway and Cell Cycle, Mitotic. GO annotations related to this gene include DNA-directed RNA polymerase activity and RNA polymerase I activity.

UniProtKB/Swiss-Prot for POLR1A Gene

  • DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic core component of RNA polymerase I which synthesizes ribosomal RNA precursors. Forms the polymerase active center together with the second largest subunit. A single stranded DNA template strand of the promoter is positioned within the central active site cleft of Pol I. A bridging helix emanates from RPA1 and crosses the cleft near the catalytic site and is thought to promote translocation of Pol I by acting as a ratchet that moves the RNA-DNA hybrid through the active site by switching from straight to bent conformations at each step of nucleotide addition (By similarity).
