NCIt definition : Human CTTN wild-type allele is located within 11q13 and is approximately 38 kb in
length. This allele, which encodes Src substrate cortactin protein, plays a role in
regulating the interactions between components of adherens-type junctions and in organizing
the cytoskeleton and cell adhesion structures of epithelia and carcinoma cells. Aberrant
regulation of this gene contributes to tumor cell invasion and metastasis, and it
is overexpressed in breast cancer and squamous cell carcinomas of the head and neck.;
