Domain

RNA polymerase Rpb7, N-terminal (IPR005576)

Short name: RNA_pol_Rpb7_N

Domain relationships

None.

Description

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].

This entry represents the N-terminal, heterodimerisation domain of RPB7.
