Cortactin (Src Substrate Cortactin, EMS1, Amplaxin, CTTN, Oncogene EMS1)

Cortactin is a c-src substrate associated with sites of dynamic actin assembly at the leading edge of migrating cells promotes branched actin filament network formation by Arp2:3 complex. Cortactin is an F-actin-binding protein. The amino-terminal half of the protein is comprised of multiple copies of an internal, tandem 37aa repeat while the carboxyl-terminal half contains a distal SH3 domain. Cortactin, present in several different cell types, is enriched in cortical structures such as membrane ruffles and lamellipodia. The properties of cortactin indicate its importance for microfilament-membrane interactions as well as transducing signals from the cell surface to the cytoskeleton. Human cortactin gene is localized on chromosome 11q13.\n\nApplications:\nSuitable for use in Western Blot.
