General description
Cortactin is encoded by the CTTN gene on chromosome 11 in humans. It is a cytoskeleton protein that facilitates assembly of cortical actin. It is expressed in most adherent cells and is a prominent substrate of protein-tyrosine kinase Src.
Immunogen
synthetic phosphopeptide derived from the region of mouse cortactin that is phosphorylated on tyrosine 421.
Application
Anti-phospho-Cortactin (pTyr421) antibody produced in rabbit is suitable for immunocytochemistry and western blotting at a working dilution of 1:1,000
Biochem/physiol Actions
Cortactin is activated by phosphorylation of tyrosine kinases or serine/threonine kinases. It plays an important role in promoting lamellipodia formation, invadopodia formation, cell migration, and endocytosis. Cortactin regulates the interactions between components of adherens-type junctions and helps in organizing the cytoskeleton, cell adhesion structures of epithelia and carcinoma cells. During apoptosis, the encoded protein is degraded in a caspase-dependent manner. It acts as a regulator in invasion and migration of tumor cells. The overexpression of cortactin causes osteosarcoma carcinogenesis and along with FAK increases the risk of oral premalignant lesions.
Physical form
Solution in Dulbecco′s phosphate buffered saline (without Mg2+ and Ca2+), pH 7.3 (+/- 0.1), 50% glycerol with 1.0 mg/mL bovine serum albumin (IgG and protease free) and 0.05% sodium azide.

Invadopodia, actin-based protrusions of invasive carcinoma cells that focally activate extracellular matrix-degrading proteases, are essential for the migration and intravasation of tumor cells during dissemination from the primary tumor. We have previously shown that cortactin phosphorylation at tyrosine residues, in

Invadopodia are dynamic protrusions in motile tumor cells whose function is to degrade extracellular matrix so that cells can enter into new environments. Invadopodia are specifically identified by microscopy as proteolytic invasive protrusions containing TKS5 and cortactin. The increasing complexity
