ⓘ RNA polymerase II subunit B4

DNA-directed RNA polymerase II subunit RPB4 is an enzyme that in humans is encoded by the POLR2D gene.

This gene encodes the fourth largest subunit of RNA polymerase II, the polymerase responsible for RNA synthesis in eukaryotes. In yeast, this polymerase subunit is associated with the polymerase under optimal conditions of growth and may highlight a protective role. The sequence for the ribosomal pseudogene contained in the 3 noncoding region of the transcript of this gene.
