  • IF - XAF1 Antibody (C-term) AP20645c
    Fluorescent image of Hela cells stained with XAF1 Antibody (C-term)(Cat#AP20645c). AP20645c was diluted at 1:25 dilution. An Alexa Fluor 488-conjugated goat anti-rabbit lgG at 1:400 dilution was used as the secondary antibody (green). Cytoplasmic actin was counterstained with Alexa Fluor® 555 conjugated with Phalloidin (red).
  • WB - XAF1 Antibody (C-term) AP20645c
    Western blot analysis of lysates from human liver and spleen tissue lysate(from left to right), using XAF1 Antibody (C-term)(Cat. #AP20645c). AP20645c was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysates at 35ug per lane.

Additional Information
Gene ID 54739
Other Names XIAP-associated factor 1, BIRC4-binding protein, XAF1, BIRC4BP, XIAPAF1
Target/Specificity This XAF1 antibody is generated from a rabbit immunized with a KLH conjugated synthetic peptide between 235-269 amino acids from the C-terminal region of human XAF1.
Dilution IF~~1:25
WB~~1:1000
Format Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.
StorageMaintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsXAF1 Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name XAF1
Synonyms BIRC4BP, XIAPAF1
Function Seems to function as a negative regulator of members of the IAP (inhibitor of apoptosis protein) family. Inhibits anti- caspase activity of BIRC4. Induces cleavage and inactivation of BIRC4 independent of caspase activation. Mediates TNF-alpha- induced apoptosis and is involved in apoptosis in trophoblast cells. May inhibit BIRC4 indirectly by activating the mitochondrial apoptosis pathway. After translocation to mitochondra, promotes translocation of BAX to mitochondria and cytochrome c release from mitochondria. Seems to promote the redistribution of BIRC4 from the cytoplasm to the nucleus, probably independent of BIRC4 inactivation which seems to occur in the cytoplasm. The BIRC4-XAF1 complex mediates down-regulation of BIRC5/survivin; the process requires the E3 ligase activity of BIRC4. Seems to be involved in cellular sensitivity to the proapoptotic actions of TRAIL. May be a tumor suppressor by mediating apoptosis resistance of cancer cells.
Cellular Location Cytoplasm. Nucleus. Mitochondrion. Note=Found in the cytoplasm and nucleus of placental syncytiotrophoblasts. Translocates to mitochondria upon TNF-alpha treatment Isoform 5: Nucleus.
Tissue Location Widely expressed. Expression is frequently down-regulated in cancer cell lines. Isoform 5 is widely expressed. Expressed in placenta (at protein level)
