POLR2E

polymerase (RNA) II (DNA directed) polypeptide E, 25kDa

On chromosome: 19p13.3
Known also as: RPB5; XAP4; RPABC1; hRPB25; hsRPB5;


NCBI Gene ID: 5434
NCBI Ensembl Id: ENSG00000099817
MIM Id: (from NCBI OMIM database) 180664
Species: Homo sapiens

This gene encodes the fifth largest subunit 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 and is present in two-fold molar excess over the other polymerase subunits. An interaction between this subunit and a hepatitis virus transactivating protein has been demonstrated, suggesting that interaction between transcriptional activators and the polymerase can occur through this subunit. A pseudogene is located on chromosome 11. [provided by RefSeq]
