RNA polymerase II, Rpb4 (IPR005574)

Short name: RNA_pol_II_Rpb4

Overlapping homologous superfamilies

Family relationships


The eukaryotic RNA polymerase subunits RPB4 and RPB7 form a heterodimer that reversibly associates with the RNA polymerase II core. Archaeal cells contain a single RNAP made up of about 12 subunits, displaying considerable homology to the eukaryotic RNAPII subunits. The RPB4 and RPB7 homologues are called subunits F and E, respectively, and have been shown to form a stable heterodimer. While the RPB7 homologue is reasonably well conserved, the similarity between the eukaryotic RPB4 and the archaeal F subunit is barely detectable [PMID: 11741548].
