In molecular biology this protein domain represents Tbf5 which stands for TTDA subunit of TFIIH basal transcription factor complex (also known as subunit 5 of RNA polymerase II transcription factor B) and Rex1 a type of nucleotide excision repair (NER) proteins. Nucleotide excision repair is a major pathway for repairing UV light-induced DNA damage in most organisms. The function of this protein is to aid transcription.
