Our Abpromise guarantee covers the use of ab87209 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
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 28 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 2.5 µg/ml.


  • FunctionAdapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner. When bound to KRT17, regulates protein synthesis and epithelial cell growth by stimulating Akt/mTOR pathway. May also regulate MDM2 autoubiquitination and degradation and thereby activate p53/TP53.
    p53-regulated inhibitor of G2/M progression.
  • Tissue specificityPresent mainly in tissues enriched in stratified squamous keratinizing epithelium.
  • Sequence similaritiesBelongs to the 14-3-3 family.
  • Post-translational
    Ubiquitinated. Ubiquitination by RFFL induces proteasomal degradation and indirectly regulates p53/TP53 activation.
  • Cellular localizationCytoplasm. Nucleus. Secreted. May be secreted by a non-classical secretory pathway.
