'''Structure of the armadillo repeat domain of plakophilin 1'''

[https://www.uniprot.org/uniprot/PKP1_HUMAN PKP1_HUMAN] Defects in PKP1 are the cause of ectodermal dysplasia-skin fragility syndrome (EDSFS) [MIM:[https://omim.org/entry/604536 604536]; 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.

The p120ctn subfamily of armadillo domain proteins has roles in modulating intercellular adhesion by cadherin-containing junctions. We have determined the crystal structure of the arm repeat domain from plakophilin-1 (PKP1), a member of the p120ctn subfamily that is found in desmosomes. The structure reveals that the domain has nine instead of the expected ten arm repeats. A sequence predicted to be an arm repeat is instead a large insert which serves as a wedge that produces a significant bend in the overall domain structure. Structure-based sequence alignments indicate that the nine repeats and large insert are common to this subfamily of armadillo proteins. A prominent basic patch on the surface of the protein may serve as a binding site for partners of these proteins.
