About POLR3B

Cytogenetic location: 12q23.3 Genomic coordinates (GRCh38): 12:106,357,748-106,510,198 (from NCBI)

This gene has 4 transcripts (splice variants), 214 orthologues, 2 paralogues and is associated with 8 phenotypes. Ubiquitous expression in esophagus (RPKM 2.4), thyroid (RPKM 2.3) and 25 other tissues.

Summary

This gene encodes the second largest subunit of RNA polymerase III, the polymerase responsible for synthesizing transfer and small ribosomal RNAs in eukaryotes. The largest subunit and the encoded protein form the catalytic center of RNA polymerase III. Mutations in this gene are a cause of hypomyelinating leukodystrophy. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]
