一般描述
Cortactin is an F-actin binding protein. It belongs to a highly conserved family of perimembrane signaling protein. Cortactin contains a unique multi-domain structure consisting of 6.5 tandem repeats of a 37-amino acid sequence required for direct binding to F-actin, followed by an α-helix region, a proline-rich region, and three tyrosine residues targeted by Src related kinases. The C-terminal region contains a Src-homology 3 (SH3) domain.
Cortactin is encoded by the CTTN gene on chromosome 11 in humans. It is expressed in most adherent cells and is a prominent substrate of protein-tyrosine kinase Src. The protein localizes within lamellipodia and at the cell surface. Cortactin is also called as EMS1.
免疫原
synthetic peptide corresponding to the mid-region of human cortactin (amino acids 361-380) conjugated to KLH.
应用
Anti-Cortactin (KE-20) antibody produced in rabbit is suitable for indirect immunofluorescence at a dilution of 1:500 using mouse fibroblasts NIH3T3 cell line and western blotting at a dilution of 1:1,000 using cytosol extract of rat brain, whole extract of chicken embryo fibroblasts, or whole cell extract of the human epidermoid carcinoma A431 cell line.
生化/生理作用
Cortactin is a cytoskeleton protein that facilitates the assembly of cortical actin. It is activated by phosphorylation of tyrosine kinases or serine/threonine kinases. It plays an important role in promoting lamellipodia formation, invadopodia formation, cell migration, and endocytosis. Cortactin regulates the interactions between components of adherens-type junctions and helps in organizing the cytoskeleton, cell adhesion structures of epithelia and carcinoma cells. During apoptosis, the encoded protein is degraded in a caspase-dependent manner. It acts as a regulator in invasion and migration of tumor cells. Overexpression of cortactin causes osteosarcoma carcinogenesis and along with FAK increases the risk of oral premalignant lesions.

Activation of Arp2/3 complex-mediated actin polymerization by cortactin
Nature Cell Biology, 3(3), 259-259 (2001)

Tyrosine phosphorylation evokes functional changes in a variety of ion channels. Modulation of the actin cytoskeleton also affects the function of some channels. Little is known about how these avenues of ion channel regulation may interact. We report that the
Cortactin (CTTN) overexpression in osteosarcoma correlates with advanced stage and reduced survival.
Cancer biomarkers : section A of Disease markers, 10(1), 35-41 (2012-02-03)
The cortactin (CTTN) gene has been found, by transcriptomic profiling, to be overexpressed in pediatric osteosarcoma. The location of CTTN at 11q13 and the role of cortactin in cytoskeleton restructuring make CTTN of interest as a potential biomarker for osteosarcoma.
Cortactin is a sensitive biomarker relative to the poor prognosis of human hepatocellular carcinoma.
World journal of surgical oncology, 11, 74-74 (2013-03-23)
Cortactin is an important regulator involved in invasion and migration of hepatocellular carcinoma (HCC). The aim of this study was to elucidate the forecasting role of cortactin in resectable HCCs. We compared the invasiveness and motility among liver epithelial cell
The Biochemical journal, 382(Pt 1), 13-25 (2004-06-10)
Cortactin was first identified over a decade ago, and its initial characterization as both an F-actin binding protein and v-Src substrate suggested that it was likely to be a key regulator of actin rearrangements in response to tyrosine kinase signalling.
