FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that anchors intermediate filaments to desmosomal plaques and forms an obligate component of functional desmosomes. Mutations in this gene are the cause of several cardiomyopathies and keratodermas, including skin fragility-woolly hair syndrome. Alternative splicing results in multiple transcript variants.

PHENOTYPE: Homozygous targeted null mutants die by embryonic day E6.5 due to instability of desmosomes and tissue integrity; rescue by aggregation with wild-type tetraploid morulae increase embyronic survival with noted major defects in heart muscle, neuroepithelium and epidermis; conditional knockouts that are epidermal-specific have compositionally altered epidermal desmosomes.
