AIFM1 Antibody (N-term)

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

     
  • IF - AIFM1 Antibody (N-term) AP8910a
    Fluorescent image of U251 cells stained with AIFM1 (N-term) antibody. U251 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min). Cells were then incubated with AP8910a AIFM1 (N-term) primary antibody (1:200, 2 h at room temperature). For secondary antibody, Alexa Fluor® 488 conjugated donkey anti-rabbit antibody (green) was used (1:1000, 1h). Cytoplasmic actin was counterstained with Alexa Fluor® 555 (red) conjugated Phalloidin (5.25 μM, 25 min). Pictures were taken on a Biorevo microscope (BZ-900, Keyence). Nuclei were counterstained with Hoechst 33342 (blue) (10 μg/ml, 5 min). AIFM1 (N-term) immunoreactivity is localized to the cytoplasm of U251 cells.
  • IF - AIFM1 Antibody (N-term) AP8910a
    Fluorescent confocal image of U251 cells stained with AIFM1 (N-term) antibody. U251 cells were treated with Chloroquine (50 μM,16h), then fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min). Cells were then incubated with AP8910a AIFM1 (N-term) primary antibody (1:200, 2 h at room temperature). For secondary antibody, Alexa Fluor® 488 conjugated donkey anti-rabbit antibody (green) was used (1:1000, 1h). Nuclei were counterstained with Hoechst 33342 (blue) (10 μg/ml, 5 min). AIFM1 (N-term) immunoreactivity is localized to the cytoplasm of U251 cells.
  • WB - AIFM1 Antibody (N-term) AP8910a
    Western blot analysis of AIFM1 Antibody (N-term) (Cat. #AP8910a) in 293 cell line lysates (35ug/lane). AIFM1 (arrow) was detected using the purified Pab.
  • IHC-P - AIFM1 Antibody (N-term) AP8910a
    Formalin-fixed and paraffin-embedded human brain tissue reacted with AIFM1 Antibody (N-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
  • FC - AIFM1 Antibody (N-term) AP8910a
    AIFM1 Antibody (N-term) (Cat. #AP8910a) flow cytometric analysis of 293 cells (right histogram) compared to a negative control cell (left histogram).FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

Protein Information
Name AIFM1
Synonyms AIF, PDCD8
Function Functions both as NADH oxidoreductase and as regulator of apoptosis. In response to apoptotic stimuli, it is released from the mitochondrion intermembrane space into the cytosol and to the nucleus, where it functions as a proapoptotic factor in a caspase-independent pathway. In contrast, functions as an antiapoptotic factor in normal mitochondria via its NADH 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.
Cellular Location Mitochondrion intermembrane space. Mitochondrion inner membrane. Cytoplasm. Nucleus. Cytoplasm, perinuclear region. Note=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 Isoform 5: Cytoplasm
Tissue Location Detected in muscle and skin fibroblasts (at protein level). Isoform 5 is frequently down-regulated in human cancers.

Background

AIFM1 is a flavoprotein essential for nuclear disassembly in apoptotic cells that is found in the mitochondrial intermembrane space in healthy cells. Induction of apoptosis results in the translocation of this protein to the nucleus where it effects chromosome condensation and fragmentation. In addition, this protein induces mitochondria to release the apoptogenic proteins cytochrome c and caspase-9.
