GenomicsGenome binding profile of TFIIH helicases XPB and XPD in HT1080 cells
The conserved TFIIH helicases XPB and XPD play key roles in transcription initiation and DNA repair. To investigate the functions of these helicases on a genome-wide scale, we performed ChIP-seq of endogenous XPB and XPD in the HT1080 human fibrosarcoma cell line. 2 ChIP samples and 1 unenriched inp...

ProteomicsDevelopment of A Image-based High-content Screening Assay Based on Clickable Probes for Identification of XPB Inhibitors
High-content screening (HCS) has become a powerful tool in drug discovery; however, their reliance on indirect readouts and surrogate markers limits their ability to directly assess drug-protein interactions at endogenous levels, particularly in subcellular contexts. Here, we report the development ...

ProteomicsSystematic mutagenesis of TFIIH subunit p52/Tfb2 identifies residues required for XPB/Ssl2 subunit function and genetic interactions with TFB6
TFIIH is an evolutionarily conserved complex that plays central roles in both RNA polymerase II (pol II) transcription and DNA repair. As an integral component of the pol II Pre-Initiation Complex (PIC), TFIIH regulates pol II enzyme activity in numerous ways. The TFIIH subunit XPB/Ssl2 is an ATP-de...

TranscriptomicsStably-paused genes revealed through inhibition of transcription initiation by the TFIIH inhibitor Triptolide
Transcription by RNA Polymerase II (Pol II) in metazoan is regulated in several steps, including preinitiation complex (PIC) formation, initiation, Pol II escape, productive elongation, cotranscriptional RNA-processing and termination. Genome-wide studies have demonstrated that the phenomenon of ...

Human immunodeficiency virus (HIV) transcription requires assembly of cellular transcription factors at the human immunodeficiency virus type 1 (HIV-1) promoter. The TFIIH general transcription factor facilitates transcription initiation by opening the DNA strands around the transcription start site...
