ID:ERCC3_HUMAN DESCRIPTION: RecName: Full=TFIIH basal transcription factor complex helicase XPB subunit; EC=3.6.4.12; AltName: Full=Basic transcription factor 2 89 kDa subunit; Short=BTF2 p89; AltName: Full=DNA excision repair protein ERCC-3; AltName: Full=DNA repair protein complementing XP-B cells; AltName: Full=TFIIH basal transcription factor complex 89 kDa subunit; Short=TFIIH 89 kDa subunit; Short=TFIIH p89; AltName: Full=Xeroderma pigmentosum group B-complementing protein; FUNCTION: ATP-dependent 3'-5' DNA helicase, component of the core- TFIIH basal transcription factor, involved in nucleotide excision repair (NER) of DNA and, when complexed to CAK, in RNA transcription by RNA polymerase II. Acts by opening DNA either around the RNA transcription start site or the DNA damage. CATALYTIC ACTIVITY: ATP + H(2)O = ADP + phosphate. SUBUNIT: One of the 6 subunits forming the core-TFIIH basal transcription factor which associates with the CAK complex composed of CDK7, CCNH/cyclin H and MNAT1 to form the TFIIH basal transcription factor. Interacts with PUF60. Interacts with ATF7IP. Interacts with Epstein-Barr virus EBNA2. INTERACTION: P62195:PSMC5; NbExp=4; IntAct=EBI-1183307, EBI-357745; P62196:Psmc5 (xeno); NbExp=6; IntAct=EBI-1183307, EBI-357713; P54727:RAD23B; NbExp=2; IntAct=EBI-1183307, EBI-954531; Q01831:XPC; NbExp=2; IntAct=EBI-1183307, EBI-372610; SUBCELLULAR LOCATION: Nucleus. DISEASE: Defects in ERCC3 are the cause of xeroderma pigmentosum complementation group B (XP-B) [MIM:610651]; also known as xeroderma pigmentosum II (XP2) or XP group B (XPB) or xeroderma pigmentosum group B combined with Cockayne syndrome (XP-B/CS). Xeroderma pigmentosum is an autosomal recessive pigmentary skin disorder characterized by solar hypersensitivity of the skin, high predisposition for developing cancers on areas exposed to sunlight and, in some cases, neurological abnormalities. Some XP-B patients present features of Cockayne syndrome, including dwarfism, sensorineural deafness, microcephaly, mental retardation, pigmentary retinopathy, ataxia, decreased nerve conduction velocities. DISEASE: Defects in ERCC3 are a cause of trichothiodystrophy photosensitive (TTDP) [MIM:601675]. TTDP is an autosomal recessive disease characterized by sulfur-deficient brittle hair and nails, ichthyosis, mental retardation, impaired sexual development, abnormal facies and cutaneous photosensitivity correlated with a nucleotide excision repair (NER) defect. Neonates with trichothiodystrophy and ichthyosis are usually born with a collodion membrane. The severity of the ichthyosis after the membrane is shed is variable, ranging from a mild to severe lamellar ichthyotic phenotype. There are no reports of skin cancer associated with TTDP. SIMILARITY: Belongs to the helicase family. RAD25/XPB subfamily. SIMILARITY: Contains 1 helicase ATP-binding domain. SIMILARITY: Contains 1 helicase C-terminal domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
