plakophilin 1 Seems to play a role in junctional plaques. Contributes to epidermal morphogenesis. Defects in PKP1 are the cause of ectodermal dysplasia- skin fragility syndrome (EDSFS); also known as McGrath syndrome. Ectodermal dysplasia defines a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. EDSFS is characterized by features of both cutaneous fragility and congenital ectodermal dysplasia affecting abnormalities in other epithelia or tissues. Desmosomes in the skin are small and poorly formed with widening of keratinocyte intercellular spaces and perturbed desmosome/keratin intermediate filament interactions. Belongs to the beta-catenin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
