Cortactin is an 80/85kD cytoskeleton protein that facilitates assembly of cortical actin.
Cortactin is widely expressed in most adherent cells and is a prominent substrate of protein-tyrosine kinase Src in vivo and in vitro.
The protein sequence of cortactin contains multiple amino-terminal tandem repeats of a unique 37aa sequence, which associates with actin, and a Src homology 3 (SH3) domain at the carboxyl terminus.
Between the repeat and the SH3 domain, there is an a-helical structure followed by a proline-rich region.
Between the proline-rich region and the SH3 domain, there are a series of Src phosphorylation sites (Tyr-421, Tyr-470, and Tyr-486).
In vitro, cortactin binds to and cross-links F-actin into meshworks.
