Activating transcription factor 6, also known as ATF6, is a protein that, in humans, is encoded by the ATF6 gene^[5][6][7] and is involved in the unfolded protein response.

Function

ATF6 is an endoplasmic reticulum (ER) stress-regulated transmembrane transcription factor that activates the transcription of ER molecules.^[8] Accumulation of misfolded proteins in the Endoplasmic Reticulum results in the proteolytic cleavage of ATF6. The cytosolic portion of ATF6 will move to the nucleus and act as a transcription factor to cause the transcription of ER chaperones.
