Gene ID: 25885 | Gene type: protein coding

About POLR1A

Cytogenetic location: 2p11.2 Genomic coordinates (GRCh38): 2:86,020,216-86,105,886 (from NCBI)

This gene has 15 transcripts (splice variants), 212 orthologues, 2 paralogues and is associated with 3 phenotypes. Ubiquitous expression in testis (RPKM 5.9), endometrium (RPKM 5.1) and 25 other tissues.

Summary

The protein encoded by this gene is the largest subunit of the RNA polymerase I complex. The encoded protein represents the catalytic subunit of the complex, which transcribes DNA into ribosomal RNA precursors. Defects in this gene are a cause of the Cincinnati type of acrofacial dysostosis. [provided by RefSeq, May 2016]
