Plakoglobin Antibody / Gamma Catenin

It recognizes a protein of 80-87kDa, identified as gamma-Catenin or Plakoglobin. The catenins (α, β, γ 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. α 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. α T-catenin binds to α E-catenin as well as to β-catenin, and it functions to inhibit Wnt signaling. CTNNA3, the gene that encodes for α-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.
