This gene encodes the seventh largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. In yeast, the association of this subunit with the polymerase under suboptimal growth conditions indicates it may play a role in regulating polymerase function.<ref>{{cite web | title = Entrez Gene: POLR2G polymerase (RNA) II (DNA directed) polypeptide G| url = https://www.ncbi.nlm.nih.gov/gene?Db=gene&Cmd=ShowDetailView&TermToSearch=5436}}</ref>
