It recognizes a protein of 80-87kDa, identified as gamma-Catenin or Plakoglobin. The catenins (alpha, beta, gamma and δ) are ubiquitously expressed, cytoplasmic proteins that associate with E-cadherin at cellular junctions. Catenin/cadherin complexes play an important role in mediating cellular adhesion. alpha T-catenin, also referred to as VR22, is a 895-amino acid protein that is most abundantly expressed in cardio-myocytes and in the peritubular myoid cells of the testis. alpha T-catenin binds to alpha E-catenin as well as to beta-catenin, and it functions to inhibit Wnt signaling. CTNNA3, the gene that encodes for alpha-T-catenin, is located on chromosome 10, and mutations in this gene show a strong correlation to late-onset Alzheimer s disease (LOAD) as well as to dilated cardiomyopathy.

Store the Plakoglobin antibody at 2-8°C (with azide) or aliquot and store at -20°C or colder (without azide).
