Protein function (UniProt)

Desmocollin-2

A component of desmosome cell-cell junctions which are required for positive regulation of cellular adhesion (PubMed:33596089). Promotes timely incorporation of DSG2 into desmosome intercellular junctions and promotes interaction of desmosome cell junctions with intermediate filament cytokeratin, via modulation of DSP phosphorylation (PubMed:33596089). Plays an important role in desmosome-mediated maintenance of intestinal epithelial cell intercellular adhesion strength and barrier function (PubMed:33596089). Positively regulates wound healing of intestinal mucosa via promotion of epithelial cell migration, and also plays a role in mechanotransduction of force between intestinal epithelial cells and extracellular matrix (PubMed:31967937). May contribute to epidermal cell positioning (stratification) by mediating differential adhesiveness between cells that express different isoforms. May promote p38MAPK signaling activation that facilitates keratinocyte migration (By similarity)
