Beta-Catenin is a 88 kDa protein which is exprimed in many different tissues. Normally it is located in the cytoplasm near the cell membrane. It is associated with E-Cadherin and it may be essential for the function of this protein. Mutations in Beta-Catenin Gen CTNNBT1 lead to a loss of membrane binding and to an accumulation of the protein in the nuclear region. Nuclear accumulation is found especially in fibromatous lesions of the breast and abdomen. Therefore the antibody has been used for differentiation of these lesions from other spindle cell tumors, which may occur in the named body regions. Nuclear Accumulation of beta-Catenin was also found in colo-rectal carcinoma. Beta-Catenin (CTNB1); Catenin (Cadherin-associated Protein) beta 1.
