CRYSTAL STRUCTURE OF THE C-TERMINAL DOMAIN OF THE RAP74 SUBUNIT OF HUMAN TRANSCRIPTION FACTOR IIF (TFIIF)CRYSTAL STRUCTURE OF THE C-TERMINAL DOMAIN OF THE RAP74 SUBUNIT OF HUMAN TRANSCRIPTION FACTOR IIF (TFIIF)
Structural highlights
Function[T2FA_HUMAN] TFIIF is a general transcription initiation factor that binds to RNA polymerase II and helps to recruit it to the initiation complex in collaboration with TFIIB. It promotes transcription elongation.[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe x-ray structure of a C-terminal fragment of the RAP74 subunit of human transcription factor (TF) IIF has been determined at 1.02-A resolution. The alpha/beta structure is strikingly similar to the globular domain of linker histone H5 and the DNA-binding domain of hepatocyte nuclear factor 3gamma (HNF-3gamma), making it a winged-helix protein. The surface electrostatic properties of this compact domain differ significantly from those of bona fide winged-helix transcription factors (HNF-3gamma and RFX1) and from the winged-helix domains found within the RAP30 subunit of TFIIF and the beta subunit of TFIIE. RAP74 has been shown to interact with the TFIIF-associated C-terminal domain phosphatase FCP1, and a putative phosphatase binding site has been identified within the RAP74 winged-helix domain.
