Predicted to enable structural molecule activity. Involved in desmosome organization; establishment of skin barrier; and heart development. Acts upstream of or within camera-type eye development; fin regeneration; and heart contraction. Predicted to be located in cytoskeleton; desmosome; and membrane. Predicted to be active in cytoplasm; intercalated disc; and plasma membrane. Predicted to colocalize with intermediate filament. Is expressed in several structures, including epidermis; head; heart; otic vesicle; and solid lens vesicle. Human ortholog(s) of this gene implicated in Carvajal syndrome; arrhythmogenic right ventricular cardiomyopathy; arrhythmogenic right ventricular dysplasia 8; dilated cardiomyopathy; and keratosis palmoplantaris striata 2. Orthologous to human DSP (desmoplakin).
