Anti-ATF6 (Clone: ABM1A40)

ATF6, also named as Cyclic AMP-dependent transcription factor ATF-6 alpha is a member of bZIP family, ATF subfamily. ATF6 forms homodimer and heterodimer with ATF6-beta. ATF6 acts by activating specific unfolded protein response target genes during endoplasmic reticulum stress. ATF6 is a ubiquitously expressed transcription factor located at endoplasmic reticulum (ER) membrane. During ER stress an approximately 50 kDa fragment containing the N-terminal cytoplasmic domain is cleaved by proteolysis and is translocated into the nucleus. N-glycosylation may serve as a sensor for ER homeostasis. For the binding of ATF6 to ERSE, ESRE should first bind to another transcription factor called Nuclear Transcription Factor Y (NF-Y). ATF6 could also be involved in activation of transcription by interacting with serum response factor. ATF6 is a 74 kDa protein and is highly expressed in kidney, liver, colon and mammary gland. Protein function: Transmembrane glycoprotein of the endoplasmic reticulum that functions as a transcription activator and initiates the unfolded protein response (UPR) during endoplasmic reticulum stress. Cleaved upon ER stress, the N-terminal processed cyclic AMP-dependent transcription factor ATF-6 alpha translocates to the nucleus where it activates transcription of genes involved in the UPR. Binds DNA on the 5'-CCAC[GA]-3'half of the ER stress response element (ERSE) (5'-CCAAT-N(9)-CCAC[GA]-3') and of ERSE II (5'- ATTGG-N-CCACG-3'). Binding to ERSE requires binding of NF-Y to ERSE. Could also be involved in activation of transcription by the serum response factor. May play a role in foveal development and cone function in the retina. [The UniProt Consortium]
