fibro-adiposis, cardiac dysfunction, and premature death. Subcellular protein fractionation and immunofluorescence showed nuclear localization of PG and PG and reduced membrane localization of PG. Coimmunoprecipitation showed reduced binding of PG but not PG to desmosome proteins DSP and DSG2. Transgene PG and PG were expressed in c-Kit :Sca1 cardiac progenitor cells (CPCs) isolated from the he...
