靶标

  • 功能

    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.

  • 疾病相关

    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.

  • 序列相似性

    Belongs to the FAD-dependent oxidoreductase family.

  • 翻译后修饰

    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.

  • 细胞定位

    Mitochondrion intermembrane space. Mitochondrion inner membrane. Cytoplasm. Nucleus. Cytoplasm > perinuclear region. Proteolytic cleavage during or just after translocation into the mitochondrial intermembrane space (IMS) results in the formation of an inner-membrane-anchored mature form (AIFmit). During apoptosis, further proteolytic processing leads to a 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. Colocalizes with EIF3G in the nucleus and perinuclear region.

Question

Hello,
just to let you know that I have tried the AIF antibody (ab32516) and blotted for CHC (ab21679) as well. When I probe the membrane for both antibodies at the same time, I do not get a band (or just a weak band, even when a high amount of protein is present), but when I probe for the proteins individually everything seems to be ok.

I think and hope that this kind of information could be added to your datasheets, so that this antibody-incompatibility does not lead to surprising results.

Best wishes,

Answer

Thank you very much for contacting us and for your feedback.

We have published this feedback in the scientific support section of the datasheet and it is now available to all the scientific community. Next, we would like to encourage you to publish Abreviews. Once published you can collect Abpoints that can be exchanged with amazon vouchers.

I hope this information will be helpful. We will look forward to receive your abreviews soon.

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.

Question

Leider ist die Chargennummer nicht mehr aufzufinden, beim Aliquotieren wurde das Originalvial leider weggeschmissen. Alles, was ich weiß ist, dass der Antikörper Anfang März 2010 bestellt wurde. Genügt das, um die Konzentration zu ermitteln? mfg

Read More
Answer

Vielen Dank für Ihre Antwort. Ich konnte anhand Ihrer Angaben die wahrscheinlichste Charge ausfindig machen: Die Konzentration Ihrer Charge ist xxxx. Ich möchte Sie darauf hinweisen, dass diese scheinbar niedrige Konzentration völlig ausreichend ist. Dieser Antikörper ist ein monoklonaler Antikörper aus dem Kaninchen. Kaninchen produzieren extrem spezifische Antikörper mit einer sehr starken Affinität und somit wird weniger Antikörper benötigt als mit monoklonalen aus der Maus. Die Menge an "Tests", die mit einem Röhrchen durchgeführt werden kann, wird von uns streng kontrolliert und immer vergleichbar gehalten. Ich hoffe, dies hilft Ihnen weiter. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.
