    PHYSICAL PROPERTIES
    STRUCTURE
    motifs/domains
  • a region of RAP 30 (the small subunit of TFIIF) with squence similarity to a sigma-factor subregion implicated in binding to RNA polymerase
  • a forkhead motif within the central region, essential for transcription, that possessed a double-stranded DNA-binding activity, and primary function of the forkhead region is dsDNA-binding in transcription with three positively charged lysine AAs which play a key role in this function
  • basic region helix-loop-helix (bHLH) motif
  • three-winged helix (WH) motifs, with one in GTF2E1 and two in GTF2E2
  • mono polymer heteromer , tetramer

    basic FUNCTION
  • ERCC3 recruitment to initiation complex
  • stimulating the RNA polymerase II C terminal domain kinase and DNA-dependent ATPase activities of ERCC3
  • plays essential roles in both transcription initiation and the transition from initiation to elongation
  • has essential roles in both transcription initiation and promoter escape
  • transcription factor essential for the assembly and stabilization of the RNA pol II pre-initiation complex (PIC) at the transcription start site
  • CELLULAR PROCESS nucleotide, transcription, initiation

    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • heterotetramer of two alpha and two beta chains
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • CDK7 thus acts through GTF2E1, GTF2E2 and SUPT5H to establish, and through CDK9 to relieve, barriers to elongation
  • IFRD1 plays essential roles in the transition step from transcription initiation to elongation by binding to melted DNA in collaboration with GTF2E2
  • IFRD1 is essential for transcription initiation by RNA polymerase II (RNA pol II) via direct interaction with the basal transcription/DNA repair factor IIH (ERCC3)
  • GTF2E2 binds to the WH domain of GTF12E1 via its bHLH domain (basic region-helix-loop-helix motif, AAs 193240)
