Application Abreviews Notes
WB 1/500 - 1/1000. Detects a band of approximately 85 kDa (predicted molecular weight: 62 kDa).
ELISA 1/20000.


  • FunctionContributes to the organization of the actin cytoskeleton and cell structure. Plays a role in the regulation of cell migration. Plays a role in the invasiveness of cancer cells, and the formation of metastases.
  • Sequence similaritiesContains 7 cortactin repeats.
    Contains 1 SH3 domain.
  • DomainThe SH3 motif may mediate binding to the cytoskeleton.
  • Post-translational
    Tyrosine phosphorylation in transformed cells may contribute to cellular growth regulation and transformation.
  • Cellular localizationCytoplasm > cytoskeleton. Cell projection > lamellipodium. Cell projection > ruffle. Associated with membrane ruffles and lamellipodia.
