IPR009025

Description

IPR009025 is a DNA-directed RNA polymerase, RBP11-like dimerisation domain.

<p>RNA polymerase (RNAP) II, which is responsible for all mRNA synthesis in eukaryotes, consists of 12 subunits. Subunits Rpb3 and Rpb11 form a heterodimer that is functionally analogous to the archaeal RNAP D/L heterodimer, and the prokaryotic RNAP alpha subunit homodimer. In each case, they play a key role in RNAP assembly by forming a platform on which the catalytic subunits (eukaryotic Rpb1/Rpb2, and prokaryotic beta/beta') can interact [[cite:PUB00013987]]. These different subunits share regions of homology. Rpb11 contains a domain (Rpb11-like domain) that is required for dimerisation, and binds to a homologous region on Rpb3. The Rpb11-like domain in Rpb11 and archaeal L subunits is contiguous, whereas in Rpb3, archaeal D, and prokaryotic alpha subunits ([interpro:IPR011263]), the Rpb11-like domain is interrupted by an insert domain ([interpro:IPR011262]). In the prokaryotic RNAP alpha subunit, the Rpb11-like domain and the insert domain form two subregions of the N-terminal domain.</p> <p>The structure of the Rpb11-like domain consists of a two-layer α/β fold consisting of β(2)-α-β(2)-α. Rpb3 and Rpb11 in yeast RNAP [[cite:PUB00008731], [cite:PUB00013986], [cite:PUB00097382]] have been shown to share a high degree of sequence and structural similarity to the alpha subunit of bacterial RNAP [[cite:PUB00005231], [cite:PUB00011749]].</p>
