Ercc2 Gene Excision Repair Cross Complementation Group 2 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
ERCC2 (Excision Repair Cross-Complementation Group 2), also known as XPD (Xeroderma Pigmentosum Group D), is a DNA repair gene encoding a DNA helicase subunit involved in nucleotide excision repair (NER). The ERCC2 protein is a critical component of the transcription factor TFIIH complex, which is essential for both transcription initiation and DNA repair.

ERCC2/XPD is an ATP-dependent DNA helicase belonging to the RAD3/XPD family. It functions as the 5' to 3' helicase subunit within the TFIIH complex (Core TFIIH). The TFIIH complex has dual roles:
ERCC2/XPD interacts with other TFIIH subunits including:
Mutations in ERCC2 cause Xeroderma Pigmentosum complementation group D (XP-D), characterized by:
Some ERCC2 mutations can cause Cockayne Syndrome (CS), particularly when combined with XP features:
While primarily known for its role in XP, ERCC2 deficiency may contribute to:
ERCC2 is expressed ubiquitously throughout the body, with high expression in:
ERCC2/XPD inhibitors are being explored as:
Potential approaches include:
The study of Ercc2 Gene Excision Repair Cross Complementation Group 2 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.
