Gene Information

General description

8-kDa trichothiodystrophy group A (p8/TTD-A) protein is the tenth subunit of general transcription factor IIH (TGFIIH). It is present as both, bound to transcription factor IIH (TFIIH) as well as a free fraction that shuffles between the cytoplasm and nucleus. The p8/TTD-A gene is located on the human chromosome at 6q25.3.

Specificity

Anti-p8/TTD-A (N-terminal) specifically recognizes human, rat, and mouse p8/TTD-A.

Application

Anti-p8/TTD-A (N-terminal) antibody produced in rabbit may be used in immunoblotting and immunofluorescence.

Biochem/physiol Actions

The 8-kDa trichothiodystrophy group A (p8/TTD-A) protein is required for the stability of the transcription factor IIH (TFIIH) complex. The cells from patients with p8/TTD-A have reduced levels of TFIIH while overexpressing p8/TTD-A restored the cellular level TFIIH complex. Defects in the p8/TTD-A gene are responsible for the third group of the sun-sensitive form of trichothiodystrophy (TTD), a rare autosomal recessive disorder.

Target description

p8/TTD-A (N-terminal) encodes a subunit of transcription/repair factor TFIIH, which functions in gene transcription and DNA repair. This protein stimulates ERCC3/XPB ATPase activity to trigger DNA opening during DNA repair, and is implicated in regulating

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2–8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
