This gene encodes a member of the desmocollin protein subfamily. Desmocollins, along with desmogleins, are cadherin-like transmembrane glycoproteins that are major components of the desmosome. Desmosomes are cell-cell junctions that help resist shearing forces and are found in high concentrations in cells subject to mechanical stress. This gene is found in a cluster with other desmocollin family members on chromosome 18. Mutations in this gene are associated with arrhythmogenic right ventricular dysplasia-11, and reduced protein expression has been described in several types of cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2015]
DSC2 (Desmocollin 2) is a Protein Coding gene. Diseases associated with DSC2 include Arrhythmogenic Right Ventricular Dysplasia, Familial, 11 and Familial Isolated Arrhythmogenic Ventricular Dysplasia, Biventricular Form. Among its related pathways are Arrhythmogenic right ventricular cardiomyopathy and Developmental Biology. Gene Ontology (GO) annotations related to this gene include calcium ion binding and cell adhesive protein binding involved in bundle of His cell-Purkinje myocyte communication. An important paralog of this gene is DSC3.
