• Application Notes: WB: 1:500-1:2000; Peptide ELISA: 1:20,000-1:40,000
• Immunogen: A synthesized peptide derived from human ATF6, corresponding to a region within the internal amino acids.
• Conjugation: Unconjugated
• Fragment: Fab fragment
• Post Translational Modifications: During unfolded protein response, a fragment of approximately 50kDa containing the cytoplasmic transcription factor domain is released by proteolysis. The cleavage seems to be performed sequentially by site-1 and site-2 proteases.N-glycosylated. The glycosylation status may serve as a sensor for ER homeostasis, resulting in ATF6 activation to trigger the unfolded protein response (UPR).Phosphorylated in vitro by MAPK14/P38MAPK.
• Subunit Structure: Homodimer and heterodimer with ATF6-beta. The dimer interacts with the nuclear transcription factor Y (NF-Y) trimer through direct binding to NF-Y subunit C (NF-YC). Interacts also with the transcription factors GTF2I, YY1 and SRF. Interacts (via lumenal domain) with THBS1 (By similarity). Interacts with THBS4 (via EGF-like 3; calcium-binding domain) which facilitates its processing, activation and nuclear translocation. Interacts with XBP1 isoform 2; the interaction occurs in a ER stress-dependent manner.
• Similarity: The basic domain functions as a nuclear localization signal.The basic leucine-zipper domain is sufficient for association with the NF-Y trimer and binding to ERSE.Belongs to the bZIP family. ATF subfamily.
• Subcellular Location: Endoplasmic reticulum membrane>Single-pass type II membrane protein. Nucleus.; Note: Under ER stress the cleaved N-terminal cytoplasmic domain translocates into the nucleus. THBS4 promotes its nuclear shuttling.
• Preparation and Storage: Store at -20 degree C. Stable for 12 months from date of receipt.

Related Product Information for anti-ATF6 antibody

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.

NCBI Description

This gene encodes a transcription factor that activates target genes for the unfolded protein response (UPR) during endoplasmic reticulum (ER) stress. Although it is a transcription factor, this protein is unusual in that it is synthesized as a transmembrane protein that is embedded in the ER. It functions as an ER stress sensor/transducer, and following ER stress-induced proteolysis, it functions as a nuclear transcription factor via a cis-acting ER stress response element (ERSE) that is present in the promoters of genes encoding ER chaperones. This protein has been identified as a survival factor for quiescent but not proliferative squamous carcinoma cells. There have been conflicting reports about the association of polymorphisms in this gene with diabetes in different populations, but another polymorphism has been associated with increased plasma cholesterol levels. This gene is also thought to be a potential therapeutic target for cystic fibrosis. [provided by RefSeq, Aug 2011]
