POLR2K

DNA-directed RNA polymerases I, II, and III subunit RPABC4 is a protein that in humans is encoded by the "POLR2K" gene.
This gene encodes one of the smallest subunits of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. This subunit is shared by the other two DNA-directed RNA polymerases.
Interactions.
POLR2K has been shown to interact with POLR2C.
