Anti-Activating Transcription Factor-6, CT, (ATF6)

Description:, Disruptions of protein folding and maturation in the endoplasmic reticulum (ER) result in the activation of the unfolded protein response (UPR), an integrated cellular signaling pathway that transmits information from the ER lumen to the cytoplasm and nucleus. Activating transcription factor 6 (ATF6) as well as the ER- transmembrane protein kinases IRE1p and PERK are the , major transducers of the UPR (1). ATF6 is an ER transmembrane protein that is normally bound to the ER chaperone GRP78, but upon ER stress is released from GRP78 and proteolytically cleaved to yield a cytosolic fragment which then migrates to the nucleus, and together with the transcription factor XBP-1, activates transcription of UPR-responsive genes (2-4). ATF6 has two isoforms (ATF6alpha and ATF6beta), only ATF6alpha is recognized by this antibody, Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 0.5-1ug'ml, Optimal dilutions to be determined by the researcher. Positive Control: MCF7 cell lysate, Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer., ,
