- Hsu S, Lai H, Jinn T. Cytosol-localized heat shock factor-binding protein, AtHSBP, functions as a negative regulator of heat shock response by translocation to the nucleus and is required for seed development in Arabidopsis. Plant Physiol. 2010;153:773-84 pubmed publisher..Protoplast two-hybrid assay results confirmed that AtHSBP interacts with itself and with the HSFs, AtHSFA1a, AtHSFA1b, and AtHSFA2. AtHSBP also negatively affected AtHSFA1b DNA-binding capacity in vitro...

Genet Mol Res. 2014;13:1233-43 pubmed publisherArabidopsis (Arabidopsis thaliana) group A1 heat shock factors (Hsfs), including HsfA1a, are important regulators in the heat shock response...
- Czarnecka Verner E, Pan S, Salem T, Gurley W. Plant class B HSFs inhibit transcription and exhibit affinity for TFIIB and TBP. Plant Mol Biol. 2004;56:57-75 pubmed..In vitro binding studies were consistent with this pattern of activity since the BD region alone interacted strongly with TFIIB, and the presence of RD had an inhibitory effect on TFIIB binding and transcriptional activation. ..
