• Product name
    Anti-ASAP2 (phospho Y724) antibody
    See all ASAP2 primary antibodies
  • Description
    Rabbit polyclonal to ASAP2 (phospho Y724)
  • Host species
  • Specificity
    Lysates prepared from COS cells overexpressing human wild-type ASAP2 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 ASAP2 blocks the signal, and the signal is absent when mutant ASAP2 extracts are used, demonstrating the specificity of the antibody.
  • Tested applications

  • Concentration information loading...
  • Purity
    Immunogen affinity purified
  • Purification notes
    This 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 ASAP2 protein. The final product is generated by affinity chromatography using a ASAP2 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).


  • Function
    Activates 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 specificity
    Detected in heart, brain, placenta, kidney, monocytes and pancreas.
  • Sequence similarities
    Contains 2 ANK repeats.
    Contains 1 Arf-GAP domain.
    Contains 1 PH domain.
    Contains 1 SH3 domain.
  • Domain
    The 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 localization
    Cytoplasm. Golgi apparatus > Golgi stack membrane. Cell membrane. Colocalizes with F-actin and ARF6 in phagocytic cups.
