{"symbol":"POLR2D","synonyms":["HSRBP4","RBP4","RPB16","HSRPB4"],"name":"polymerase (RNA) II (DNA directed) polypeptide D","description":"This gene encodes the fourth largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. In yeast, this polymerase subunit is associated with the polymerase under suboptimal growth conditions and may have a stress protective role. A sequence for a ribosomal pseudogene is contained within the 3\u0027 untranslated region of the transcript from this gene.
