GTF2H1 polyclonal antibody

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. In NER, TFIIH acts by opening DNA around the lesion to allow the excision of the damaged oligonucleotide and its replacement by a new DNA fragment. In transcription, TFIIH has an essential role in transcription initiation. When the pre-initiation complex (PIC has been established, TFIIH is required for promoter opening and promoter escape. Phosphorylation of the C-terminal tail (CTD of the largest subunit of RNA polymerase II by the kinase module CAK controls the initiation of transcription.

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE) .
