Preparation and Storage

Background: Desmocollin-2

DSC-2 (Desmocollin [Greek for "glue-that-binds"]-2; also epithelial type 2 desmocollin) is a 100-120 kDa member of the Ca⁺⁺-dependent cadherin family of adhesion molecules. It is found on the surface of both simple and stratified epithelium that form desmosomes. DSC-2 expression is induced by DSG-2 where it serves as a component of desmosomes, forming a linkage that unites adjacent cells with cytoplasmic intermediate filaments. Homodimeric DSC-2 forms in-trans, and DSC-2 may also form heterotypic interactions with DSG-2. A DSC-2:DSG-2 cis-interaction is suggested to block DSG-2 activation of Akt, an action that results in beta -catenin mediated cell proliferation. Mature mouse DSC-2 is a 767 amino acid (aa) type I transmembrane glycoprotein (aa 136-902). The mature molecule contains a 559 aa extracellular region (aa 136-694) with five cadherin domains (aa 136-694) and a 187 aa cytoplasmic tail (aa 716-902). There is one 100-110 kDa splice variant that shows an 11 aa substitution for aa 838-902. Over aa 136-694, mouse DSC-2 shares 87% and 79% aa sequence identity with rat and human DSC-2, respectively.
