Gene Information

human ... HSF1(3297)

Biochem/physiol Actions

A transcriptional factor that mediates the expression of heat shock proteins by binding to a heat shock response element located upstream from the heat shock protein genes. In unstressed cells HSF-1 is non-DNA binding protein that rapidly converts to the transcriptionally active form in response to heat and heavy metals.

Physical form

in 25 mM Tris pH 8.0, 150 mM NaCl, 2 mM DTT

The existence of multiple heat shock factor (HSF) genes in higher eukaryotes has promoted questions regarding the functions of these HSF family members, especially with respect to the stress response. To address these questions, we have used polyclonal antisera raised
