Anti-PAG3 (phospho Y724) antibody (ab18031)


  • Product nameAnti-PAG3 (phospho Y724) antibody
    See all PAG3 primary antibodies
  • Description
    Rabbit polyclonal to PAG3 (phospho Y724)
  • SpecificityLysates prepared from COS cells overexpressing human wild-type PAG3 and cotransfected with mouse Pyk2 were immunoblotted in the presence of non-phosphopeptide corresponding to the immunogen, a generic phosphotyrosine-containing peptide or the phosphopeptide immunogen. The data show that only the peptide corresponding to phospho Y724 PAG3 blocks the signal, and the signal is absent when mutant PAG3 extracts are used, demonstrating the specificity of the antibody.
  • Tested applicationsSuitable for: WBmore details
  • Species reactivity
    Reacts with human PAG3 Predicted to react with mouse PAG3 due to 92% sequence homology
  • Immunogen

    Synthetic phosphopeptide derived from the region of human PAG3 that contains tyrosine 724.

  • Positive control
    • COS cells overexpressing human wild type PAG3, cotransfected with mouse Pyk2.


  • FormLiquid
  • Storage instructionsShipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
  • Storage bufferPreservative: 0.05% Sodium Azide
    Constituents: 50% Glycerol, PBS (without Mg2+ and
    Ca2+), 1mg/ml BSA. pH 7.3.
  • Concentration information loading...
  • PurityImmunogen affinity purified
  • Purification notesThis antibody was purified from rabbit serum by sequential epitope specific chromatography. The antibody has been negatively preadsorbed using a non phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non phosphorylated PAG3 protein. The final product is generated by affinity chromatography using a PAG3 derived peptide that is phosphorylated at tyrosine 724.

Application Abreviews Notes
WB 1/1000. Detects a band of approximately 160 kDa (predicted molecular weight: 112 kDa).


  • FunctionActivates the small GTPases ARF1, ARF5 and ARF6. Regulates the formation of post-Golgi vesicles and modulates constitutive secretion. Modulates phagocytosis mediated by Fc gamma receptor and ARF6. Modulates PXN recruitment to focal contacts and cell migration.
  • Tissue specificityDetected in heart, brain, placenta, kidney, monocytes and pancreas.
  • Sequence similaritiesContains 2 ANK repeats.
    Contains 1 Arf-GAP domain.
    Contains 1 PH domain.
    Contains 1 SH3 domain.
  • DomainThe conserved Arg-464 in the Arf-GAP domain probably becomes part of the active site of bound small GTPases and is necessary for GTP hydrolysis.
  • Post-translational
    Phosphorylated on tyrosine residues by SRC and PTK2B.
  • Cellular localizationCytoplasm. Golgi apparatus > Golgi stack membrane. Cell membrane. Colocalizes with F-actin and ARF6 in phagocytic cups.

    Western blot using Ab18031 on COS cell lysate overexpressing human PAG3.

    Lane 1: wild-type PAG3 alone
    Lane 2: wild-type PAG3 cotransfected with mouse PyK2
    Lane 3: wild-type PAG3 cotransfected with mouse PyK2. Antibody blocked with the non phosphopeptde corresponding to the immunogen
    Lane 4: wild-type PAG3 cotransfected with mouse PyK2. Antibody blocked with the generic phosphotyrosine corresponding to the immunogen
    Lane 5: wild-type PAG3 cotransfected with mouse PyK2. Antibody blocked with the generic phosphopeptide immunogen
    Lane 6: mutant [Y724/Y763] PAG3 cotransfected with Pyk2

    10-30 micrograms of cell lysate can be loaded when using similar lysates with this antibody. Samples were run using SDS-PAGE on a 8% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer for one hour at room temperature, then incubated with PAG3 antibody Ab18031 for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with blocking peptides. After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG HRP conjugate in 3% BSA-TBST buffer, and bands were detected using the Pierce SuperSignal method.

    Only the phospho peptide immunogen blocks the antibody, confirming its specificity for the phospho epitope tyrosine 724.
