ATF6B (S425) polyclonal antibody

ATF-6 is a member of the basic-leucine zipper family of transcription factors. Endoplasmic reticulum stress causes cleavage of transmembrane ATF-6 and transclocation of active ATF-6 to the nucleus. Soluble ATF-6 can exist as either an ATF-6β homodimer or an ATF-6α/β heterodimer. Binding of the ATF-6β homodimer or ATF-6α/β heterodimer to the nuclear transcription factor Y C (NF-YC) induces ER chaperone transcription.
