Beschreibung

Allgemeine Beschreibung

Cortactin is an F-actin binding protein. It belongs to a highly conserved family of perimembrane signaling protein. Cortactin contains a unique multi-domain structure consisting of 6.5 tandem repeats of a 37-amino acid sequence required for direct binding to F-actin, followed by an α-helix region, a proline-rich region, and three tyrosine residues targeted by Src related kinases. The C-terminal region contains a Src-homology 3 (SH3) domain.

Cortactin is encoded by the CTTN gene on chromosome 11 in humans. It is expressed in most adherent cells and is a prominent substrate of protein-tyrosine kinase Src. The protein localizes within lamellipodia and at the cell surface. Cortactin is also called as EMS1.

Immunogen

synthetic peptide corresponding to the mid-region of human cortactin (amino acids 361-380) conjugated to KLH.

Anwendung

Anti-Cortactin (KE-20) antibody produced in rabbit is suitable for indirect immunofluorescence at a dilution of 1:500 using mouse fibroblasts NIH3T3 cell line and western blotting at a dilution of 1:1,000 using cytosol extract of rat brain, whole extract of chicken embryo fibroblasts, or whole cell extract of the human epidermoid carcinoma A431 cell line.

Biochem./physiol. Wirkung

Cortactin is a cytoskeleton protein that facilitates the assembly of cortical actin. It 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. Overexpression of cortactin causes osteosarcoma carcinogenesis and along with FAK increases the risk of oral premalignant lesions.
