Our Abpromise guarantee covers the use of ab33542 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
  • Application notesIP: Use at a concentration of 4 µg/ml (immunoprecipitated IQGAP1 from 500µg of a HepG2 RIPA lysate).
    WB: Use at a concentration of 1 µg/ml. Predicted molecular weight: 184 kDa. A goat anti-mouse secondary antibody conjugated to HRP can be used as secondary antibody together with a chemiluminescence detection system.

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionBinds to activated CDC42 but does not stimulate its GTPase activity. It associates with calmodulin. Could serve as an assembly scaffold for the organization of a multimolecular complex that would interface incoming signals to the reorganization of the actin cytoskeleton at the plasma membrane. May promote neurite outgrowth.
    • Tissue specificityExpressed in the placenta, lung, and kidney. A lower level expression is seen in the heart, liver, skeletal muscle and pancreas.
    • Sequence similaritiesContains 1 CH (calponin-homology) domain.
      Contains 4 IQ domains.
      Contains 1 Ras-GAP domain.
      Contains 1 WW domain.
    • DomainRegions C1 and C2 can either interact with nucleotide-free CDC42, or interact together, depending on the phosphorylation state of Ser-1443. When Ser-1443 is not phosphorylated, C1 and C2 interact, which prevents binding of nucleotide-free CDC42 and promotes binding of GTP-bound CDC42. Phosphorylation of Ser-1443 prevents interaction between C1 and C2, which opens the structure of the C-terminus and allows binding and sequestration of nucleotide-free CDC42 on both C1 and C2.
    • Post-translational
      Phosphorylation of Ser-1443 by PKC prevents interaction between C1 and C2, allowing binding of nucleotide-free CDC42. Ser-1443 phosphorylation enhances the ability to promote neurite outgrowth.
    • Cellular localizationCell membrane.
