    EXPRESSION
    Rna function mRNAs were abundant in both dorsolateral prefrontal cortex and hippocampus, with a distinct neuronal localization^, without the distinct laminar patterns seen for CTNNA2 and CTNNB1 but distinctly localized in the granule cells of the dentate gyrus and pyramidal cells of Ammon horn

    basic FUNCTION
  • alpha cadherin and desmoglein, transducing wingless signals
  • regulating cell adhesion
  • signaling molecule with roles in desmosome assembly and development and in regulation of gene expression
  • acting as a potent modulator of epithelial homeostasis via its role as a key suppressor of c-Myc
  • also a structural constituent of desmosomes, where it binds to the cytoplasmic domains of the desmosomal cadherins, desmogleins and desmocollins
  • required for correct maintenance of skin integrity, but have distinct roles in the epidermis and heart
  • arterial intima-enriched (AIE) gene, with periplakin, SPRR3, envoplakin, galectin 7, and plakoglobin that are functionally related in that they contribute to the stress properties of stratified epithelium
