Description générale
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.
Immunogène
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
Actions biochimiques/physiologiques
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.

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
Cortactin is a sensitive biomarker relative to the poor prognosis of human hepatocellular carcinoma.

Cortactin is an important regulator involved in invasion and migration of hepatocellular carcinoma (HCC). The aim of this study was to elucidate the forecasting role of cortactin in resectable HCCs. We compared the invasiveness and motility among liver epithelial cell
Cortactin (CTTN) overexpression in osteosarcoma correlates with advanced stage and reduced survival.

The cortactin (CTTN) gene has been found, by transcriptomic profiling, to be overexpressed in pediatric osteosarcoma. The location of CTTN at 11q13 and the role of cortactin in cytoskeleton restructuring make CTTN of interest as a potential biomarker for osteosarcoma.

Cortactin was first identified over a decade ago, and its initial characterization as both an F-actin binding protein and v-Src substrate suggested that it was likely to be a key regulator of actin rearrangements in response to tyrosine kinase signalling.

Cortactin is a branched actin regulator and tumor-overexpressed protein that promotes vesicular trafficking at a variety of cellular sites, including endosomes and the trans-Golgi network. To better understand its role in secretory trafficking, we investigated its function in Golgi homeostasis.
