Summary: This gene encodes a member of the cadherin family of proteins that forms an integral transmembrane component of desmosomes, the multiprotein complexes involved in cell adhesion, organization of the cytoskeleton, cell sorting and cell signaling. The encoded preproprotein undergoes proteolytic processing to generate a mature, functional protein. Mice lacking the encoded protein die in utero. Mutant mice lacking a part of the extracellular adhesive domain of the encoded protein develop cardiac fibrosis and dilation. This gene is located in a cluster of desmosomal cadherin genes on chromosome 18. [provided by RefSeq, Jan 2016]

Dsg2 expression dramatically enhances the rate of spontaneous basal cell carcinoma (BCC) formation in mouse models of Gorlin syndrome. In vitro studies showed that Dsg2 potentiates canonical hedgehog (Hh) signaling and Stat3 activation in ASZ001 BCC cells in both an autocrine and paracrine manner. Data showed that Dsg2 induces a paracrine mediator that stimulates the canonical Hh signaling through Stat3.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
