Immunogen Synthetic peptide
Specificity The synthetic peptide sequence used to generate the antibody AP2501a is PLVRVKEEPPSPPQSPR, containing a predicted sumoylation site from the central region of human HSF1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
Alternative Name HSF1
Background Heat shock transcription factor 1 (HSF1) mediates the induction of heat shock protein gene expression in cells exposed to elevated temperature and other stress conditions. In response to stress, HSF1 acquires DNA-binding ability and localizes to nuclear stress granules. SUMO modification of HSF1 converts HSF1 to the DNA-binding form. HSF1 colocalizes with SUMO-1 in nuclear stress granules, which is prevented by mutation of the HSF1 lysine targeted for sumoylation.
