XPB
From Wikipedia, the free encyclopedia
XPB (Xeroderma Pigmentosum B) is an ATP dependent human DNA helicase that is a part of the TFIIH transcription factor complex.
Structure
The 3D structure of the archeael homologue of XPB has been solved by X-ray crystallography by Dr. John Tainer and his group at The Scripps Research Institute.[1]
Function
XPB plays a significant role in normal basal transcription, transcription coupled repair (TCR), and nucleotide excision repair (NER). Purified XPB has been shown to unwind DNA with 3’-5’polarity.
Disorders
Mutations in XPB and other related complementation groups, XPA-XPG, leads to a number of genetic disorders such as Xeroderma Pigmentosum, Cockayne's syndrome, and Trichothiodystrophy.
Interactions
XPB has been shown to interact with XPC,[2] BCR gene,[3] ERCC2,[4][5][6][7] P53,[8] GTF2H2,[4][5] GTF2H1,[4][5][9] GTF2H5,[4] Cyclin-dependent kinase 7,[4][9][10] PSMC5[11] and GTF2H4.[4][5]
