ATF6


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

Function

ATF6 is an endoplasmic reticulum stress-regulated transmembrane transcription factor that activates the transcription of ER molecules. 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.

Interactions

ATF6 has been shown to interact with YY1 and Serum response factor.
