  • 機能

    Probable oxidoreductase that has a dual role in controlling cellular life and death; during apoptosis, it is translocated from the mitochondria to the nucleus to function as a proapoptotic factor in a caspase-independent pathway, while in normal mitochondria, it functions as an antiapoptotic factor via its oxidoreductase activity. The soluble form (AIFsol) found in the nucleus induces 'parthanatos' i.e., caspase-independent fragmentation of chromosomal DNA. Interacts with EIF3G,and thereby inhibits the EIF3 machinery and protein synthesis, and activates casapse-7 to amplify apoptosis. Plays a critical role in caspase-independent, pyknotic cell death in hydrogen peroxide-exposed cells. Binds to DNA in a sequence-independent manner.

  • 関連疾患

    Defects in AIFM1 are the cause of combined oxidative phosphorylation deficiency type 6 (COXPD6) [MIM:300816]. It is a mitochondrial disease resulting in a neurodegenerative disorder characterized by psychomotor delay, hypotonia, areflexia, muscle weakness and wasting.

  • 配列類似性

    Belongs to the FAD-dependent oxidoreductase family.

  • 翻訳後修飾

    Under normal conditions, a 54-residue N-terminal segment is first proteolytically removed during or just after translocation into the mitochondrial intermembrane space (IMS) by the mitochondrial processing peptidase (MPP) to form the inner-membrane-anchored mature form (AIFmit). During apoptosis, it is further proteolytically processed at amino-acid position 101 leading to the generation of the mature form, which is confined to the mitochondrial IMS in a soluble form (AIFsol). AIFsol is released to the cytoplasm in response to specific death signals, and translocated to the nucleus, where it induces nuclear apoptosis in a caspase-independent manner.

Question

I am interested in looking at AIF as a potential marker of caspase-independent apoptosis. Please can you tell me if this is a reliable marker or if there is another product you would recommend? I don’t see any caspase cleavage but I do see mitochondrial membrane depolarisation and membrane blebbing in my experiments suggesting that some other form of death is occurring.

Also, to use it for this purpose would it be best to look for it in mitochondrial and nuclear fractions by immunoblotting as I presume that FACS & standard immunoblotting would only tell you if it was present in the cell or not or do levels increase after mitochondrial release? Would your cellular fractionation kit ab109719 be suitable for looking at AIF in these fractions?

I am working with rat cells, which of your antibodies is best for this cell type: ab119917, ab32516 or ab1998?

Sorry this is not an area that I am familiar with!

Thanks

Answer

Thank you for contacting us.

I would suggested searching the potential of this as caspase-independent apoptosis marker in publications. There are many publications related to this protein. Please have a look in pubmed.

As the process triggering apoptosis involves the mitochondrial release of AIF through the mitochondrial membrane, which enters the cytosol, and finally ends up in the cell nucleus where it signals the cell to condense its chromosomes and fragment its DNA molecules in order to prepare for cell death. So the idea would be to compare the AIF level in mitochondrial, cytosolic and nuclear preparations. The kit ab109719 should be able to separate the mitochondrial, cytosolic and nuclear fractions for experiment.

Monoclonal antibodies provide clean WB results so monoclonal will be best suitable e.g. ab119917 and ab32516. This however does not mean polyclonal aren't good, they are good but monoclonal are better.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Answer



ab1998 : https://www.abcam.com/ab1998, where the immunogen is described asa peptide corresponding to amino acids 517 to 531 of human AIF. This sequence is identical tothose of mouse and rat AIF.

ab32042 : https://www.abcam.com/ab32042, where the immunogen is described as : a synthetic peptide corresponding to residues following Ser29 of human Caspase 3 (N terminus of p17 subunit).

ab59348 : https://www.abcam.com/ab59348, where the immunogen is described as a synthesized non phosphopeptide derived from human Bcl2 around the phosphorylation site of threonine 69 (ARTPSP).

Question

I´ve been following this problem, even though in this particular Ab I´m not the final user. First of all the concentration the data sheet suggested is the one used from the beginning, also incubation times has been tested ( 1 hour at RT or ON at 4 ºC) so the problem is not that we have a weak band , it is that there is no band at all (even at 4 ºC ON) so we believe your Ab is not working. On the other hand we bought at the same time the COX IV loading control which works fine at the concentration suggested on the data sheet and 1 hour at RT. Increasing Ab concentrations is would be possible if we see a weak signal...remember we have not signal even at ON incubations and it is different to data sheet suggestions and what we expected on this Ab at the time we choose it. More over Carlos thesis work has been done mainly using western blot experiments on same model so I´m clear that we have not problems on the technique.

Answer

Thank you for your email. In your prior message with the attachment containing the Western blot image, incubation for 1 hr at RT was mentioned but not overnight at 4C. I agree with you and I would expect that you would see some sort of signal with your samples and overnight incubation. As we guarantee our products to work as stated on the online datasheet, I would be happy to offer you a free of charge replacement vial or a credit note or refund. Please let me know how you would like to proceed, and happy holidays!

BATCH NUMBER 108063 ORDER NUMBER 112828 DESCRIPTION OF THE PROBLEM No signal (No band at all) SAMPLE Purified Rat liver Mitochondria PRIMARY ANTIBODY AB 1998 DETECTION METHOD Super signal west pico (pierce) POSITIVE AND NEGATIVE CONTROLS USED We have tried just rat liver mitochondria lysates using triton x 100, SDS or NP 40. This is my model, and the release of cytochrome c works fine, so I am not interested in other species. ANTIBODY STORAGE CONDITIONS The antibody was Aliquoted upon arrival and store at -30 ?C SAMPLE PREPARATION lysis buffer containing PMSF 1 mM, EDTA 10 mM, Nacl 300 mM, BME 5 mM, NP40 1 %,Tris 50 mM (pH: 7.6) plus protease inhibitors cocktail. AMOUNT OF PROTEIN LOADED 5-30 ?g per lane ELECTROPHORESIS/GEL CONDITIONS Std 12 %SDS-PAGE, run at 170 volts during 1 hour. TRANSFER AND BLOCKING CONDITIONS Wet transfer, 25 volts over night. Blocking solution: 5 % Non fat milk in TBS. 1 Hour RT. SECONDARY ANTIBODY Goat anti-Rabbit- HRP conjugated (AP 132P, Chemicon) HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 4 HAVE YOU RUN A "NO PRIMARY" CONTROL? No WHAT STEPS HAVE YOU ALTERED? NONE ADDITIONAL NOTES I have experience with several anti-bodies. For most of them the western blot condition are the same with not troubles of any kind. I am investigating the release of apoptotic factors from isolated mitochondria induced by Bax. The detection in this experiments of cytochrome c works fine. But now I wanted to try AIF release in this model. But the AB 1998 anti-body did not work.

Answer

Thank you for your enquiry and I'm sorry to hear that you are experiencing difficulty with ab1998. At this time I would like to make the following suggestions in order to help improve your results. I would suggest extending the incubation period with the primary antibody to overnight at 4C and also increasing the concentration of ab1998 to 1:500. I also suggest running a positive control - K562 cell lysate is recommended for ab1998. Please contact us again if you have any additional questions, and happy holidays.
