Description: Homo sapiens general transcription factor IIH, polypeptide 5 (GTF2H5), mRNA. RefSeq Summary (NM_207118): This gene encodes a subunit of transcription/repair factor TFIIH, which functions in gene transcription and DNA repair. This protein stimulates ERCC3/XPB ATPase activity to trigger DNA opening during DNA repair, and is implicated in regulating cellular levels of TFIIH. Mutations in this gene result in trichothiodystrophy, complementation group A. [provided by RefSeq, Mar 2009]. Sequence Note: This RefSeq record was created from transcript and genomic sequence data to make the sequence consistent with the reference genome assembly. The genomic coordinates used for the transcript record were based on transcript alignments. Transcript (Including UTRs) Position: hg19 chr6:158,589,379-158,620,376 Size: 30,998 Total Exon Count: 3 Strand: + Coding Region Position: hg19 chr6:158,591,536-158,613,189 Size: 21,654 Coding Exon Count: 2
ID:TF2H5_HUMAN DESCRIPTION: RecName: Full=General transcription factor IIH subunit 5; AltName: Full=General transcription factor IIH polypeptide 5; AltName: Full=TFB5 ortholog; AltName: Full=TFIIH basal transcription factor complex TTD-A subunit; FUNCTION: Component of the TFIIH basal transcription factor involved in nucleotide excision repair (NER) of DNA and, when complexed to CAK, in RNA transcription by RNA polymerase II. Necessary for the stability of the TFIIH complex and for the presence of normal levels of TFIIH in the cell. SUBUNIT: Subunit of the TFIIH basal transcription factor complex that contains ERCC2, ERCC3, GTF2H1, GTF2H2, GTF2H3, GTF2H4, GTF2H5, MNAT1, CDK7 and CCNH. SUBCELLULAR LOCATION: Nucleus. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. DISEASE: Defects in GTF2H5 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 TFB5 family.
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.
