• Host: Rabbit
• Reactivity: Human
• Clonality: Polyclonal
• Specificity: The antibody was cross adsorbed to unphosphorylated AIFM1 (Ser-116) peptide before affinity purification using phospho-AIFM1 (Ser-116) peptide. This antibody antibody detects a triplet at 66, 62, and 57kDa* protein on SDS-PAGE immunoblots of human Jurkat cells treated with calyculin A. This reactivity is not observed after lambda phosphatase treatment to dephosphorylated AIFM1.
• Form/Format: Rabbit polyclonal, affinity-purified antibody is supplied in 100ul phosphate-buffered saline, 50% glycerol, 1mg/ml BSA, and 0.05% sodium azide.

• Applicable Applications for anti-AIFM1 antibody: Western Blot (WB), ELISA (EIA)
• Application Notes: ELISA: 1:2000; WB: 1:1000
• Immunogen: Phospho-AIFM1 (Ser-116) synthetic peptide (coupled to carrier) corresponding to amino acids surrounding Ser-116 in human AIFM1. This site is conserved in rat and mouse AIFM1, but the amino acids surrounding the site are not well conserved. The site is not found in AIFM2 and AIFM3.
• Preparation and Storage: Store at -20 degree C. Stable for 1 year.

Western Blot (WB)

(Western blot image of human jurkat cells untreated (lanes 1 & 3) or treated with calyculin A (100nM, 30 min.) (lanes 2 and 4). The blot was probed with rabbit polyclonals anti-AIFM1 (C-terminal region) at 1:500 (lanes 1 & 2) and anti-AIFM1 (Ser-116) phospho-specific antibody at 1:1000 (lanes 3 & 4).)

Related Product Information for anti-AIFM1 antibody

Apoptosis-inducing factor (AIFM1, AIF, PDCD8) is a ubiquitously expressed flavoprotein that plays a critical role in caspase-independent apoptosis. AIFM1 is expressed as a 66kDa precursor protein before being N-terminally cleaved to 62kDa and localized to the mitochondrial intermembrane space. In response to apoptotic stimuli, AIFM1 is released from the mitochondrial intermembrane as a 57kDa fragment that can translocate to the nucleus. Treatment of isolated nuclei with recombinant AIFM1 leads to early apoptotic events, such as chromatin condensation and large-scale DNA fragmentation. Studies of AIFM1 knockout mice have shown that the apoptotic activity of AIFM1 is cell type and stimuli-dependent. AIFM1 has been implicated in oxeiptosis, a non-inflammatory, caspase independent cell death pathway caused by oxidative stress. During oxeiptosis, increased reactive oxygen species cause the release of the phosphatase PGAM5 from KEAP1 leading to dephosphorylation of AIFM1 (Ser-116) and subsequent cell death. Thus, AIFM1 phosphorylation status at Ser-116 may be an important marker for cell death involving oxeiptosis.

NCBI Description

This gene encodes a flavoprotein essential for nuclear disassembly in apoptotic cells, and it 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 affects chromosome condensation and fragmentation. In addition, this gene product induces mitochondria to release the apoptogenic proteins cytochrome c and caspase-9. Mutations in this gene cause combined oxidative phosphorylation deficiency 6, which results in a severe mitochondrial encephalomyopathy. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 10. [provided by RefSeq, May 2010]

Uniprot Description

PDCD8: 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. Interacts with XIAP/BIRC4. Interacts (via N-terminus) with EIF3G (via C-terminus). Belongs to the FAD-dependent oxidoreductase family. 4 isoforms of the human protein are produced by alternative splicing.
