Cortactin and phosphorylated cortactin tyr466 expression in temporal bone carcinoma

Cortactin is a multidomain protein engaged in several cellular mechanisms involving actin assembly and cytoskeletal arrangement. Cortactin overexpression in several malignancies has been associated with increased cell migration, invasion, and metastatic potential. Cortactin needs to be activated by tyrosine or serine/threonine phosphorylation. The role of cortactin and phosphorylated cortactin (residue tyr466) was investigated in temporal bone squamous cell carcinoma (TBSCC).
