Description

The ERCC2 helicase is primarily involved in DNA repair. It may also be involved in transcription because it is a component of the core TFIIH basal transcription factor [546].

ERCC2-null mice die at embryonic stages [1762]. Mutations in ERCC2 that reduce its activity in mice appear to accelerate ageing and increase cancer incidence. The mutant mice live on average less than a year, display growth retardation, enhanced apoptosis, and start to develop a phenotype resembling premature aging at about 3-4 months of age that becomes increasingly more severe. Combining mutations in ERCC2 with XPA ablation results in a much more severe phenotype [14]. Surprisingly, however, combining different mutations in ERCC2 ameliorates age-related phenotypes and developmental delay in mice [1857]. In humans, several pathologies have been associated with mutations in ERCC2 [191], including trichothiodystrophy and Cockayne syndrome which are characterized by progeroid-like features. As such, ERCC2 may play a role in human ageing.
