It's conformation is of alpha-helices 12-16 plus a short beta-bridge to the FeS-cluster domain at the N-terminal. The full-length XPD protein verifies the presence of damage to DNA and allows DNA repair to proceed. XPD is an assembly of several domains to form a doughnut-shaped molecule that is able to separate two DNA strands and scan the DNA for damage. HBB helps to form the overall DNA-clamping architecture [1]. This family represents a conserved region within a number of eukaryotic DNA repair helicases (EC:3.6.1.-).

Prokaryotes contain a single RNA polymerase compared to three in eukaryotes (not including mitochondrial. and chloroplast polymerases). Rpb2 is the second largest subunit of the RNA polymerase. This domain comprised of the structural domains anchor and clamp [1]. The clamp region (C-terminal) contains a zinc-binding motif [1]. The clamp region is named due to its interaction with the clamp domain found in Rpb1. The domain also contains a region termed "switch 4". The switches within the polymerase are thought to signal different stages of transcription [1].

This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at least one of the subunits contacted by the transcription factor TIF-IA [2].

The 3' endonuclease XPG is a major component of the nucleotide excision repair machinery. The structure of the N-terminal domain reveals that it adopts a pleckstrin homology (PH) fold [1,2]. This PH-type domain has been shown to bind to a mono-phosphorylated inositide [2].
