機能
Transcription factor that acts during endoplasmic reticulum stress by activating unfolded protein response target genes. 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. -
組織特異性
Ubiquitous. -
配列類似性
Belongs to the bZIP family. ATF subfamily.
Contains 1 bZIP domain. -
ドメイン
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. -
翻訳後修飾
During unfolded protein response an approximative 50 kDa fragment 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. -
細胞内局在
Endoplasmic reticulum membrane and Nucleus. Under ER stress the cleaved N-terminal cytoplasmic domain translocates into the nucleus. - Information by UniProt

ChIC/CUT&RUN was performed using a pAG-MNAse at a final concentration of 700 ng/mL, 2 x 10^5 HeLa cells treated with Thapsigargin (0.5 µM for 24h) and 5µg of ab227830 [EPR22690-84]. The resulting DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 10 million reads. The negative IgG control ab172730 is also shown.

Predicted band size: 74 kDa
Observed band size: 90 kDa why is the actual band size different from the predicted?ab227830 was shown to specifically react with ATF6 in wild-type HAP1 cells as signal was lost in ATF6 knockout cells. Wild-type and ATF6 knockout samples were subjected to SDS-PAGE. ab227830 and ab181602 (Rabbit anti-GAPDH loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/200,000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/20,000 dilution for 1 hour at room temperature before imaging.Exposure time 62 seconds.Blocking/Diluting buffer and concentration: 5% NFDM/TBST. -

Observed band size: 50,90 kDa why is the actual band size different from the predicted?ATF6 is cleaved upon ER stress and the molecular weight observed is consistent with what has been described in the literature (PMID: 25149687; 11163209).Exposure time 3 minutes.Blocking and diluting buffer and concentration: 5% NFDM/TBST. -
ATF6 was immunoprecipitated from 0.35 mg HeLa (human cervix adenocarcinoma epithelial cell) whole cell lysate with ab227830 at 1/30 dilution (2μg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab227830 1/1000 dilution (0.5 μg/ml). VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/5000 dilution.

Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 3 min.
Lysate were made freshly and used in IP test immediately to minimize protein degradation. Incubation time was 2h.

Immunohistochemical analysis of paraffin-embedded Human kidney tissue labeling ATF6 with ab227830 at 1/1000 dilution (0.566 μg/ml) followed by a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining on human kidney (PMID: 25725420) is observed. The section was incubated with ab227830 for 30 mins at room temperature.
The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20mins.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

Chromatin was prepared from HeLa cells treated with thapsigargin (1 uM, 1 h) according to the Abcam Dual-X-ChIP protocol*. Cells were fixed with 1.5 mM EGS for 30 mins and then formaldehyde for 10 min.
The ChIP was performed with 25 µg of chromatin, 5 µg of ab227830 (red), or 5 µg of rabbit normal IgG ab172730 (gray) and 20 µl of Protein A/G sepharose beads. The immunoprecipitated DNA was quantified by real time PCR (Taqman approach for active and inactive loci, Sybr green approach for heterochromatic loci).
Primers and probes are from paper PMID: 17535801.
