... [66]. The bookmarking function of HSF2 is achieved by recruitment of protein phos-phatase 2A to inhibit nearby condesin complexes by dephosphorylation. The bookmarking of the HSP70promoter and other ... bound by HSFs. Efficient trimerization of HSFs is important to establish interactions with thegap- and step-type HSEs. The different types of HSEsresult in the induction, by yeast HSFs, of different ... repression on the promoter, for example,degradation of the ncRNA repressors by an RNase,removal of the ncRNA repressors by an RNA helicase,or binding of another ncRNA to Pol II to displace thencRNA...
