Summary: Enables phosphatidylinositol-3-phosphate binding activity and phosphatidylinositol-5-phosphate binding activity. Involved in nucleotide-excision repair; transcription by RNA polymerase I; and transcription by RNA polymerase II. Located in cytosol and nucleus. Part of nucleotide-excision repair factor 3 complex; transcription factor TFIIH core complex; and transcription factor TFIIH holo complex. Orthologous to human GTF2H1 (general transcription factor IIH subunit 1). [provided by Alliance of Genome Resources, Dec 2024]

Interplay of the Tfb1 pleckstrin homology domain with Rad2 and Rad4 in transcription coupled and global genomic nucleotide excision repair.
Title: Interplay of the Tfb1 pleckstrin homology domain with Rad2 and Rad4 in transcription coupled and global genomic nucleotide excision repair.
DNA opening is catalyzed by Ssl2, the dsDNA translocase subunit of the basal transcription factor TFIIH. ATP hydrolysis by Ssl2 opens a 6-base-pair (bp) bubble that grows to 13 bp in the presence of NTPs. These observations support a two-step model wherein ATP-dependent Ssl2 translocation leads to a 6-bp open complex that RNA polymerase II expands via NTP-dependent RNA transcription.
Title: TFIIH generates a six-base-pair open complex during RNAP II transcription initiation and start-site scanning.
Structure determination of a Rad2-Tfb1PH complex indicates that Rad2 binds to TFIIH using a similar motif as TFIIEalpha uses to bind TFIIH in the pre-initiation complex.

The pleckstrin homology domain (residues 1-115) from the TFB1 subunit of TFIIH is sufficient for binding to the activation domain of herpes simplex virus protein VP16.
