High impact information on SRB5

  • In vitro transcription and template commitment assays confirm that SRB2 and SRB5 are components of a functional preinitiation complex and are required for efficient transcription initiation [1].
  • Epistasis analysis with expression-profile phenotypes shows that MED2 and MED18 are downstream of CDK8 [2].
  • Surprisingly, fusions with neither Srb5 nor Med9 circumvented TFIIE requirement for the CUP1 activation [3].
 

Analytical, diagnostic and therapeutic context of SRB5

  • Immunoprecipitation experiments with anti-SRB5 antibodies demonstrate that the acidic activating domain of VP16 specifically binds to the holoenzyme [4].
