Product Specific Information
1 µg/mL of MA5-45128 was sufficient for detection of HSF1 in 20 µg of heat-shocked HeLa cell lysate by ECL immunoblot analysis using Goat anti-rat IgG: HRP as the secondary antibody.
Detects approximately 85 kDa (unstressed cell lysates) and approximately 95 kDa (heat-shocked cell lysates).
Target Information
All organisms respond to elevated temperatures and various environmental stresses by rapid synthesis of heat shock RNAs and proteins. The transcriptional activator heat shock factor (HSF) binds to heat shock response elements (HSEs), which consist of three repeats of a 5-nucleotide {nGAAn} module.
Two HSFs have been identified in human cells: HSF1 and HSF2. They 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. Upon stress, HSF1 becomes activated to a nuclear-localized, trimeric state that binds DNA. Phosphorylation of HSF1 is necessary for maximal transcription of heat shock genes.
