Summaries for PKP1 Gene

Entrez Gene Summary for PKP1 Gene

  • 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 protein may be involved in molecular recruitment and stabilization during desmosome formation. Mutations in this gene have been associated with the ectodermal dysplasia/skin fragility syndrome. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

GeneCards Summary for PKP1 Gene

PKP1 (Plakophilin 1) is a Protein Coding gene. Diseases associated with PKP1 include Ectodermal Dysplasia/Skin Fragility Syndrome and Pkp1-Related Ectodermal Dysplasia/Skin Fragility Syndrome. Among its related pathways are Immune System and Regulation of activated PAK-2p34 by proteasome mediated degradation. GO annotations related to this gene include binding and lamin binding. An important paralog of this gene is PKP2.

  • Ectodermal dysplasia-skin fragility syndrome (EDSFS) [MIM:604536]: A form of ectodermal dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. Characterized by features of both cutaneous fragility and congenital ectodermal dysplasia affecting skin, hair and nails. There is no evidence of significant 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. Note=The disease is caused by mutations affecting the gene represented in this entry.
