DNA-directed RNA polymerase II subunit RPB11-a is an enzyme that in humans is encoded by the POLR2J gene.

Function

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. ^[5]

Interactions

POLR2J has been shown to interact with:

• Apoptosis antagonizing transcription factor, ^[6]
• POLR2C, ^{[7] [8]} and
• SATB1. ^[9]
