HSF1 antibody (pSer303)

Catalog No. ABIN197025

Product Details anti-HSF1 Antibody

Target: HSF1 (Heat Shock Factor Protein 1 (HSF1))

Binding Specificity: pSer303

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: This HSF1 antibody is un-conjugated

Application: Western Blotting (WB), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Specificity: This antibody detects endogenous levels of HSF1 only when phosphorylated at Serine 303.

Purification: Affinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.

Immunogen: The antiserum was produced against synthesized phosphopeptide derived from Human HSF1 around the phosphorylation site of Serine 303 (P-P-Sp-P-P).

Background: All organisms respond to elevated temperatures and a variety of 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 are found as three repeats of a 5-nucleotide {nGAAn} module, arranged in alternating orientation and present upstream of all heat shock genes. The HSEs are highly conserved among species yet HSF purified from yeast, Drosophila and human have different molecular weights and the proteins do not show significant immunological cross reaction. Two HSFs have been identified in human cells, HSF 1 and HSF 2, which bind to the same HSEs and have 38 % sequence identity. These factors are activated by distinct stimuli, HSF 1 is responsive to classical stress signals such as heat, heavy metals and oxidative reagents, whereas HSF 2 is activated during hemin-mediated differentiation of human erythroleukemia cells. HSF 1 exists constitutively in the cytoplasm and the nucleus of unstressed cells as a monomer which lacks DNA binding activity. Through an unknown signal generated during stress, HSF 1 becomes activated to a nuclear localized, trimeric state which binds to DNA. The phosphorylation of HSF 1 is necessary for maximal transcription of heat shock genes.Synonyms: HSF-1, HSTF1, Heat shock transcription factor 1
