POLR2C encodes the third largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The product of this gene contains a cysteine rich region and exists as a heterodimer with another polymerase subunit, POLR2J. These two subunits form a core subassembly unit of the polymerase. A pseudogene has been identified on chromosome 21. POLR2C (RNA Polymerase II Subunit C) is a Protein Coding gene. Diseases associated with POLR2C include Hiv-1. Among its related pathways are Activated PKN1 stimulates transcription of AR (androgen receptor) regulated genes KLK2 and KLK3 and DNA damage_Role of Brca1 and Brca2 in DNA repair.
