Ercc3 - excision repair cross-complementing rodent repair deficiency, complementation group 3

Enables ATP hydrolysis activity and promoter-specific chromatin binding activity. Acts upstream of or within UV protection and transcription elongation from RNA polymerase I promoter. Predicted to be located in nucleoplasm. Predicted to be part of RNA polymerase II transcription regulator complex; nucleotide-excision repair factor 3 complex; and transcription preinitiation complex. Is expressed in several structures, including brain; eye; liver; oral region epithelium; and tooth. Used to study xeroderma pigmentosum group B. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma; photosensitive trichothiodystrophy 2; trichothiodystrophy; xeroderma pigmentosum; and xeroderma pigmentosum group B. Orthologous to human ERCC3 (ERCC excision repair 3, TFIIH core complex helicase subunit). [provided by Alliance of Genome Resources, Apr 2022]
