This gene encodes a subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes.

The product of this gene exists as a heterodimer with another polymerase subunit; together they form a core subassembly unit of the polymerase.

Two similar genes are located nearby on chromosome 7q22.1 and a pseudogene is found on chromosome 7p13.
