POLR2I encodes a subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. This subunit, in combination with two other polymerase subunits, forms the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA. The product of this gene has two zinc finger motifs with conserved cysteines and the subunit does possess zinc binding activity. POLR2I (RNA Polymerase II Subunit I) is a Protein Coding gene. Diseases associated with POLR2I 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.
