When the stress is turned on, ATF-2 changes its function and induces Inheritance of Stress-Induced, ATFDependent Epigenetic Change. A typical example of epigenetics is DNA methylation, which is important for . ATF‐2 is a target of the stress‐activated protein kinase p Recently ..

Inheritance of stress-induced, ATFdependent epigenetic change. – FPrime
Atf1, the fission yeast homolog of activation transcription factor-2 ATF-2contributes to heterochromatin formation. However, the role of ATF-2 in chromatin assembly in higher organisms remains unknown. The dATF-2 protein colocalized with HP1, not only on heterochromatin but also at specific loci in euchromatin.
Heat shock or osmotic stress induced phosphorylation of dATF-2 and resulted in its release from heterochromatin. This heterochromatic disruption was an epigenetic event that was transmitted to the next generation in a non-Mendelian fashion. When embryos were exposed to heat stress over multiple generations, the defective chromatin state was maintained over multiple successive generations, though it gradually returned to the normal state.
The results suggest a mechanism by which the effects of stress are inherited epigenetically via the regulation of a tight chromatin structure.
