Description

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.
