      Alternate Names
      • Amplaxin
      • Oncogene EMS1
      • Src substrate cortactin
      Background InformationCortactin 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.

      Entrez Gene Number
      Entrez Gene SummaryThis gene is overexpressed in breast cancer and squamous cell carcinomas of the head and neck. The encoded protein is localized in the cytoplasm and in areas of the cell-substratum contacts. This gene has two roles: (1) regulating the interactions between components of adherens-type junctions and (2) organizing the cytoskeleton and cell adhesion structures of epithelia and carcinoma cells. During apoptosis, the encoded protein is degraded in a caspase-dependent manner. The aberrant regulation of this gene contributes to tumor cell invasion and metastasis. Two splice variants that encode different isoforms have been identified for this gene. [provided by RefSeq]
