Protein Information (annotations from UniProt)

Database IDHIV0012045
UniProt IDQ13216
Primary gene name(s)ERCC8
Synonym gene name(s)CKN1, CSA
Protein nameDNA excision repair protein ERCC-8
Protein functionSubstrate-recognition component of the CSA complex, a DCX, DDB1-CUL4-X-box E3 ubiquitin-protein ligase complex, involved in transcription-coupled nucleotide excision repair. The CSA complex, DCX(ERCC8 complex promotes the ubiquitination and subsequent proteasomal degradation of ERCC6 in a UV-dependent manner; ERCC6 degradation is essential for the recovery of RNA synthesis after transcription-coupled repair. It is required for the recruitment of XAB2, HMGN1 and TCEA1/TFIIS to a transcription-coupled repair complex which removes RNA polymerase II-blocking lesions from the transcribed strand of active genes. {ECO:0000269|PubMed:16751180, ECO:0000269|PubMed:16916636, ECO:0000269|PubMed:16964240}.
