General description

Cortactin is a 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 37-amino acid sequence, which associates with actin, and a Src homology 3 domain at the carboxyl terminus.

Recent research efforts show cortactin is acetylated in vivo and is deacetylated by HDAC6 (Histone deacetylase 6). HDAC6 is a tubulin-specific deacetylase that regulates microtubule-dependent cell movement. In recent studies it was demonstrated that HDAC6 binds cortactin and alters the ability of cortactin to bind F-actin by modulating a “charge patch” in its repeat region. Findings suggest that, in addition to its role in microtubule-dependent cell motility, HDAC6 influences actin-dependent cell motility by altering the acetylation status of cortactin, which, in turn, changes the F-actin binding activity of cortactin. The acetylation level of cortactin may correlate to tumor metastases and acetylated cortactin may be considered a potential metastasis marker.
