NCIt definition : Tenascin (2201 aa, 241 kDa) is encoded by the human TNC gene. This protein is involved
in neuron migration and axon guidance.;
NCIt note : Tenascin (hexabrachion, cytotactin) is an extracellular matrix protein that promotes
cell attachment with spatially and temporally restricted tissue distribution in many
developing organs. It is a hexameric, multidomain protein with disulfide-linked subunits.
A C-terminal domain is similar to fibrinogen. Tenascin also contains type III units,
similar to those in fibronectin, and EGF-like repeats. In the CNS, tenascin C is expressed
primarily by astrocytes. Tenascin expression is induced by serum as well as TGF-beta.; Hexameric extracellular matrix glycoprotein transiently expressed in many developing
organs and often re-expressed in tumors. It is present in the central and peripheral
nervous systems as well as in smooth muscle and tendons.;
