    摘要: A method is provided for determining whether an agent is capable of inducing a DNA lesion in a eukaryotic cell, including exposing the eukaryotic cell to the agent and determining whether an HR23 protein-binding molecule accumulates in the cell, where the HR23 protein-binding molecule is preferably xeroderma pigmentosum group C (XPC), 3-methyladenine DNA glycosylase (MAG), CREB, p53, or a functional part, derivative, and/or analogue thereof. Preferably the cell overexpresses HR23A and/or HR23B protein. A rapid and sensitive test is provided with significant advantages over the Ames test. A method is provided for determining whether an agent is capable of inhibiting a cellular process, the process resulting in accumulation of HR23 protein-binding molecule within a cell. A method for determining whether a cell has an impaired DNA repair system is provided. An impaired DNA repair system is indicative for diseases such as xeroderma pigmentosum, cockayne syndrome, and/or trichothiodystrophy.

    摘要: The present invention pertains to a nucleic acid sequence encoding a human TFIIH 8 kDa subunit and related sequences. The nucleic acids may be used in methods for producing a TFIIH subunit, as well as in methods for diagnosing or treating transcription and NER deficiencies, in particular in some forms of trichothiodystrophy (TTD). The hTFB5/TTDA gene and encoded protein may be used for therapy or genetherapy products, aimed at treating congenital NER disorders and may also be used in methods of diagnosis of disorders in basal transcription, NER and TCR activity in mammals, using molecular probes or antibodies specific for TTDA.
