General Transcription Factor IIH Subunit 2 (GTF2H2) is a component of the TFIIH transcription factor complex, essential for RNA polymerase II transcription and nucleotide excision repair (NER). GTF2H2 works in concert with other TFIIH subunits to facilitate DNA damage recognition and repair.
GTF2H2 is a 395-amino acid protein that forms part of the core TFIIH complex. It interacts with XPB, XPD, and other TFIIH subunits.
GTF2H2 contributes to TFIIH complex stability and function. The complex is essential for transcription initiation and NER.
In neurons, GTF2H2 maintains proper transcription of essential genes and DNA repair capacity.
GTF2H2 dysfunction may contribute to transcriptional dysregulation and DNA repair deficits in AD.
Neuronal vulnerability in PD may involve impaired GTF2H2 function.
No GTF2H2-targeted therapies exist.
The study of Gtf2H2 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
