Target Information
All organisms respond to elevated temperatures and various environmental stresses by rapid synthesis of heat shock RNAs and proteins. The regulation of heat shock gene transcription is mediated by the transcriptional activator heat shock factor (HSF), which binds to heat shock response elements (HSEs). These HSEs consist of three repeats of a 5-nucleotide {nGAAn} module arranged in alternating orientation and are present upstream of all heat shock genes.
HSFs are highly conserved among species, yet HSFs purified from yeast, Drosophila, and human have different molecular weights and show minimal immunological cross-reactivity. Two HSFs have been identified in human cells—HSF1 and HSF2—which bind to the same HSEs and share 38% sequence identity.
HSF1 responds to classical stress signals such as heat, heavy metals, and oxidative reagents, while HSF2 is activated during hemin-mediated differentiation of human erythroleukemia cells. HSF1 exists constitutively in the cytoplasm and nucleus of unstressed cells as a monomer lacking DNA binding activity. Under stress, HSF1 becomes activated to a nuclear-localized, trimeric state capable of DNA binding. Phosphorylation of HSF1 is necessary for maximal transcription of heat shock genes.
