p120 Catenin Information for Pathologists
p120 catenin is one of the transmembrane components of epithelial adherens junction proteins (J Cell Sci 2001;114:503), which includes p120 catenin and E-cadherin (Prog Mol Biol Transl Sci 2013;116:71). In the cadherin - catenin complex, which is essential for the formation of intercellular tight junctions, p120 catenin attaches to E-cadherin on the internal aspect of the cell membrane. p120 is composed of 2 domains, an external calcium dependent domain and an internal domain to which p120 catenin is bound (Oncogene 1996;13:1919) in a juxtamembranous location (J Cell Biol 1998;141:779). p120 is involved in promotion of cell junction formation, cell motility and E-cadherin trafficking and turnover. Binding of p120 to E-cadherin stabilizes the complex and increases the half-life of E-cadherin.
Common Uses By Pathologists:
Differentiation between ductal and lobular carcinoma / in situ lesions. p120 shows a membranous pattern of staining in ductal carcinoma and in situ lesions. Lack of E-cadherin staining and strong p120 cytoplasmic staining is feature of the spectrum of lobular lesions (atypical lobular hyperplasia (ALH), lobular carcinoma in situ (LCIS), lobular carcinoma). Positive cytoplasmic staining for lobular carcinoma is much easier to interpret than E-cadherin negative staining. E-cadherin and p120 catenin cocktail improve the diagnosis of in situ lesions (Int J Clin Exp Pathol 2014;7:2551).
