Cell adhesion in desmosomes

Desmoplakin is a protein in humans that is encoded by the DSP gene.[5][6][7] Desmoplakin is a critical component of desmosome structures in cardiac muscle and epidermal cells, which function to maintain the structural integrity at adjacent cell contacts. In cardiac muscle, desmoplakin is localized to intercalated discs which mechanically couple cardiac cells to function in a coordinated syncytial structure. Mutations in desmoplakin have been shown to play a role in dilated cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy, where it may present with acute myocardial injury;[8][9] striate palmoplantar keratoderma, Carvajal syndrome and paraneoplastic pemphigus.
