Anti-GTF2H3 antibodies are used in the immunodetection of the protein general transcription factor IIH subunit 3. In humans, the canonical protein has a reported length of 308 amino acid residues and a mass of 34.4 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. A member of the TFB4 protein family, GTF2H3 is a known component of the general transcription and DNA repair factor IIH (TFIIH) core complex, which is involved in general and transcription-coupled nucleotide excision repair (NER) of damaged DNA and, when complexed to CAK, in RNA transcription by RNA polymerase II. Synonyms for this target antigen include P34, TFB4, TFIIH, TFIIH basal transcription factor complex p34 subunit, basic transcription factor 2 34 kDa subunit, and BTF2. GTF2H3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the GTF2H3 antibodies listed below. In addition, Immunofluorescence is also a common application.
