Latest research from the Bäurle lab on the function of our favourite memory TF - HSFA2!
Promoter and domain swap analysis delineates heat stress memory-specific determinants of heat shock factor HSFA2
The function of the transcription factor HSFA2 in heat-stress induced transcriptional memory maps to functional domains within the protein.
