Clinical Significance:
B-catenin is normally present at the cell surface, bound to E-cadherin surface protein, participating in cell-cell structures. It is also involved in the Wnt signal transduction pathway. Abnormalities in B-catenin lead to nuclear and/or cytoplasmic accumulation of the protein, which may be seen in tumors such as fibromatosis, several sarcomas, and polyps in patients with familial adenomatous polyposis.
