DNA-directed RNA polymerases I, II, and III subunit RPABC2 is a protein that in humans is encoded by the POLR2F gene.^[1]

This gene encodes the sixth largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes, that is also shared by the other two DNA-directed RNA polymerases. In yeast, this polymerase subunit, in combination with at least two other subunits, forms a structure that stabilizes the transcribing polymerase on the DNA template.^[2]

Interactions

POLR2F has been shown to interact with POLR2C.^[3]
