GENE INFORMATION

Gene name

POLR3B (HGNC Symbol)

Synonyms

FLJ10388, RPC2

Description

Polymerase (RNA) III (DNA directed) polypeptide B (HGNC Symbol)

Entrez gene 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]
