Anti-Plakophilin 2/PKP2 Antibody Picoband® Fluoro647 Conjugated

Plakophilin-2 is a protein that in humans is encoded by the PKP2 gene. This gene encodes a member of the arm-repeat (armadillo) and plakophilin gene families. It is mapped to 12p11.21. PKP2 is a constituent of the desmosomal plaque in simple epithelia, some stratified epithelia, and some nonepithelial cells. PKP2 is also enriched in the karyoplasm of cells of various types, including those lacking desmosomes. Plakophilin proteins participate in linking cadherins to intermediate filaments in the cytoskeleton and this gene product may regulate the signaling activity of beta-catenin. PKP2 has been shown to interact with Desmoplakin, Plakoglobin and Desmoglein 1.

A synthetic peptide corresponding to a sequence at the C-terminus of human Plakophilin 2, identical to the related mouse sequence, and different from the related rat sequence by one amino acid.

Detected in heart right ventricle (at protein level) . Widely expressed. Found at desmosomal plaques in simple and stratified epithelia and in non-epithelial tissues such as myocardium and lymph node follicles. In most stratified epithelia found in the desmosomes of the basal cell layer and seems to be absent from suprabasal strata. .
