This gene encodes a member of the arm-repeat (armadillo) and plakophilin gene families. Plakophilin proteins contain numerous armadillo repeats, localize to cell desmosomes and nuclei, and participate in linking cadherins to intermediate filaments in the cytoskeleton. This gene may regulate the signaling activity of beta-catenin and is required to maintain transcription of genes that control intracellular calcium cycling including ryanodine receptor 2, ankyrin-B, triadin, and calcium channel, voltage-dependent, L type, alpha 1C. Mutations in this gene are associated with different inherited cardiac conditions including Arrythmogenic Cardiomyopathy, Brugada Syndrome, and Idiopathic Ventricular Fibrillation. A processed pseudogene with high similarity to this gene has been mapped to chromosome 12p13. [provided by RefSeq, May 2022]
A study in mice and human heart samples demonstrated that reduced levels and junctional localization of the PKP2 in arrhythmogenic cardiomyopathy (AC) leads to pathogenic activation of the Hippo pathway and enhanced adipogenesis [Chen et al. DOI:10.1161/CIRCRESAHA.114.302810]. In forensic contexts, the PKP2 gene is strongly associated with arrhythmogenic right ventricular cardiomyopathy (ARVC) and is a target for molecular autopsy via next-generation sequencing to identify pathogenic variants in cases of sudden unexplained death, often before structural changes are detectable [Sacco et al. DOI:10.3390/ijms27020670].
