      Background InformationSrc substrate cortactin (UniProt: Q14247; also known as Amplaxin, Oncogene EMS1) is encoded by the CTTN (also known as EMS) gene (Gene ID: 2017) in human. Cortactin is a peripheral membrane protein that serves as a substrate for Src tyrosine kinase and plays a role in regulating cell motility. It is shown to interact with F-actin to promote its polymerization and branching and contributes to the organization of the actin cytoskeleton and cell shape. It also plays a role in the formation of lamellipodia and in cell migration. It contains an N-terminal acidic domain, six and a half tandem repeats of a unique 37-amino acid sequence, and a C-terminal Src homology (SH3) domain. The repeat regions are shown to be essential for F-actin binding. Cortactin is activated via phosphorylation by upstream kinases in response to extracellular stimuli. In mice, Src kinase primarily phosphorylates cortactin at tyrosines 421, 466, and 482, which leads its interaction with F-actin and Arp2/3. It can also be phosphorylated by ERK on serine 405 and 418 that results in recruitment of additional actin nucleation-promoting factors (NPFs), most importantly N-WASP, to the Arp2/3/ complex. Deacetylation of cortactin by HDAC6 is reported to block its translocation to the cell periphery and block its association with F-actin and impairs cell motility. Overexpression of cortactin has been reported in many human tumors and its expression correlates well with the metastatic potential of breast cancer cells and hepatocellular carcinomas.

      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]
