HBB is the domain on DEAD-box eukaryotic DNA repair helicases (EC:3.6.1.-) that appears to be a unique fold. 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 ...
HBB is the domain on DEAD-box eukaryotic DNA repair helicases (EC:3.6.1.-) that appears to be a unique fold. 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.-).
The carboxyl-terminal region of TFIIH is essential for transcription activity. This regions binds three zinc atoms through two independent domain. The first contains a C4 zinc finger motif, whereas the second is characterised by a CX(2)CX(2-4)FCADCD ...
The carboxyl-terminal region of TFIIH is essential for transcription activity. This regions binds three zinc atoms through two independent domain. The first contains a C4 zinc finger motif, whereas the second is characterised by a CX(2)CX(2-4)FCADCD motif. The solution structure of the second C-terminal domain revealed homology with the regulatory domain of protein kinase C (Pfam:PF00130) [1].
This is the C-terminal domain of Transcription factor Tfb2 present in Saccharomyces cerevisiae. Tfb2 is referred to as p52 in humans. The interaction between p8-Tfb5 and p52-Tfb2 has a key role in the maintenance of the transcription factor TFIIH arc ...
This is the C-terminal domain of Transcription factor Tfb2 present in Saccharomyces cerevisiae. Tfb2 is referred to as p52 in humans. The interaction between p8-Tfb5 and p52-Tfb2 has a key role in the maintenance of the transcription factor TFIIH architecture and TFIIHs function in nucleotide-excision repair (NER) pathway. The C-terminal domain of Tfb2 is thought to have a crucial role in DNA repair [1].
