Description Anti-Cortactin (p80/85) Antibody, clone 4F11
Background Information Cortactin is present as a p80 and p85 kDa protein in many cell types.  The protein was first identified as being a major substrate of the tyrosine kinase pp60SRC. The main structural feature of the protein is that at the N-terminus there are five and a half 37-amino acid repeats, these appear to be responsible for the actin-binding.  This repeat region occupies about a third of the protein.  The repeat region is followed by a helical region and then a proline rich region and finally at the C-terminus, an SH3 domain.  The proline rich domain is thought to bind the SH2 domain of v-src the viral version of the normal c-src known to phosphorylate cortactin.  Cortactin bundles microfilaments and this bundling is inhibited by tyrosine phosphorylation.  One pathway that activates the pathway leading to tyrosine phosphorylation of cortactin results from a cell adhesion molecule in brain micro-vessel endothelial cells, another is the growth factor, but presumably the very many mechanisms for pp60src activation would also result in cortactin phosphorylation and subsequent loss of actin binding.

Entrez Gene Number
Entrez Gene Summary This 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.
