MA5-14622 targets Heat Shock Factor 1 in GS, IF, IP, and WB applications and shows reactivity with Human, mouse, and Rat samples.
The MA5-14622 immunogen is recombinant mouse HSF1 protein (aa1-503).
HSF1 responds to cellular stress signals such as heat, heavy metals, and oxidative reagents; binds to heat shock response elements (HSEs) in the upstream region of heat shock gene and activates their transcription. Some laboratories have reported that the constitutive, non-DNA binding, monomeric form of inactive HSF1 is located in the cytoplasm. Upon activation, HSF1 is trimerized and is localized in nucleus where it binds DNA.

Two distinct disulfide bonds formed in human heat shock transcription factor 1 act in opposition to regulate its DNA binding activity.
MA5-14622 was used in western blot to study the effects on heat shock transcription factor-1 trimerization and DNA binding of two different disulfide bonds
