Structural basis for group A trichothiodystrophy.

Abstract excerpt

Patients with the rare neurodevelopmental repair syndrome known as group A trichothiodystrophy (TTD-A) carry mutations in the gene encoding the p8 subunit of the transcription and DNA repair factor TFIIH. Here we describe the crystal structure of a minimal complex between Tfb5, the yeast ortholog of p8, and the C-terminal domain of Tfb2, the yeast p52 subunit of TFIIH. The structure revealed that these two...
