Predicted to enable several functions, including DNA binding activity; TFIID-class transcription factor complex binding activity; and promoter-specific chromatin binding activity. Predicted to contribute to 3' overhang single-stranded DNA endodeoxyribonuclease activity and DNA binding activity. Involved in cellular response to organic cyclic compound. Predicted to be located in chromosome, telomeric region and nucleus. Predicted to be part of ERCC4-ERCC1 complex and nucleotide-excision repair factor 1 complex. Human ortholog(s) of this gene implicated in Fanconi anemia complementation group Q; XFE progeroid syndrome; pancreatic cancer; xeroderma pigmentosum; and xeroderma pigmentosum group F. Orthologous to human ERCC4 (ERCC excision repair 4, endonuclease catalytic subunit). [provided by Alliance of Genome Resources, Apr 2022]
