Ercc3 Gene Summary [Mouse]
Enables ATP hydrolysis activity and promoter-specific chromatin binding activity. Acts upstream of or within UV protection and transcription elongation by RNA polymerase I. 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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Ercc3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
