TAIRmember of Heat Stress Transcription Factor (Hsf) family
UniProtTranscriptional regulator that specifically binds DNA sequence 5'-AGAAnnTTCT-3' known as heat shock promoter elements (HSE).
Function -- GeneRIF ? help Back to Top
  1. Data suggest that HsfB1 and HsfB2b may be involved in complex regulatory networks, which are linked to other stress responses and signaling processes.
    [PMID: 19945192]
  2. These data indicate that HsfB1 and HsfB2b suppress the general heat shock response under non-heat-stress conditions and in the attenuating period.
    [PMID: 21908690]
  3. The constitutive expression of HsfB2b leads to severely reduced levels of the PRR7 transcript and late flowering and elongated hypocotyls.
