Biochem/physiol Actions

TFIIH, a multi-subunit complex is involved in several biological fundamental mechanisms of the cell: transcription, nucleotide excision repair and cell cycle regulation. p62 is one of the six subunits that constitutes the core of TFIIH. Analysis of the expression of the p62 gene reveals an over-expression in testis tissue. This subunit of TFIIH participates in a variety of protein-protein interactions. For example, Rb competes with TBP and p62 for binding to E2F thus repressing E2F-mediated trans-activation; herpes simplex virus VP16 and human p53 directly interact with the p62 subunit of TFIIH. In addition, TFIIH, via p62 phosphorylation is the major target for mitotic inactivation of transcription.
