Gene: ERCC2 (ERCC excision repair 2, TFIIH core complex helicase subunit) Homo sapiens
Symbol: ERCC2
Name: ERCC excision repair 2, TFIIH core complex helicase subunit
Description: Exhibits several functions, including 5'-3' DNA helicase activity; protein C-terminus binding activity; and protein N-terminus binding activity. Contributes to DNA-dependent ATPase activity and RNA polymerase II CTD heptapeptide repeat kinase activity. Involved in several processes, including UV protection; hair cell differentiation; and nucleotide-excision repair. Localizes to several cellular components, including the CAK-ERCC2 complex; MMXD complex; and RNA polymerase II, holoenzyme. Implicated in several diseases, including acoustic neuroma; acquired immunodeficiency syndrome; endocrine gland cancer (multiple); hematologic cancer (multiple); and xeroderma pigmentosum (multiple). Biomarker of Alzheimer's disease and Down syndrome.
Type: protein-coding
RefSeq Status: REVIEWED
