| Tissue Specificity | Expressed in oral mucosa (at protein level). Expressed in arrector pili muscle (at protein level). Expressed in the heart in the heart (at protein level). Isoform DPI: Apparently an obligate constituent of all desmosomes. Isoform DPII: Resides predominantly in tissues and cells of stratified origin. |
| Post Translational Modifications | Phosphorylation at Ser-2849 increases association with intermediate filament cytokeratin, potentially facilitating interaction between desmosome junctions and intermediate filament architecture. |
| Function | Major high molecular weight protein of desmosomes. Regulates profibrotic gene expression in cardiomyocytes via activation of the MAPK14/p38 MAPK signaling cascade and increase in TGFB1 protein abundance. |
