MGI Phenotype |
FUNCTION: 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] PHENOTYPE: Homozygous mutation of this gene results in embryonic lethality before somite formation, impaired cell proliferation, and increased apoptosis. Heterozygous mutation of this gene also results in embryonic lethality before somite formation with partial penetrance. [provided by MGI curators]

Phenotypic Description |
The weg phenotype was identified among N-ethyl-N-nitrosourea (ENU)-mutagenized G3 mice of the pedigree R5503, some of which showed susceptibility to dextran sodium sulfate (DSS)-induced colitis at days 7 (Figure 1) and 10 (Figure 2) after DSS treatment.
|
Nature of Mutation |
Whole exome HiSeq sequencing of the G1 grandsire identified 99 mutations. The DSS susceptibility phenotype wax linked by continuous variable mapping to mutations in three genes on chromosome 18: Dsg2, B4galt6, Trappc8. The mutation in Dsg2 was presumed causative because DSG2 has known functions in intestinal barrier maintenance. The Dsg2 mutation is a T to A transversion at base pair 20,580,651 (v38) on chromosome 18, or base pair 22,578 in the GenBank genomic region NC_000084 encoding DSG2. The strongest association was found with a recessive model of inheritance to the DSS day 7 phenotype, wherein five variant homozygotes departed phenotypically from 18 homozygous reference mice and 23 heterozygous mice with a P value of 1.339 x 10-8 (Figure 3). The mutation corresponds to residue 889 in the mRNA sequence NM_007883 within exon 6 of 15 total exons.

Protein Prediction |
DSG2 is a member of the desmoglein (DSG) family of cadherins. Dsg2 is part of the desmosomal cadherin gene cluster on chromosome 18. The mouse genome desmosomal cadherin gene cluster includes: Dsc3 (desmocollin 3)—Dsc2—Dsc1—Dsg1β (Dsg5)—Dsg1α—Dsg1γ (Dsg6)—Dsg4 (see the record for burrito)—Dsg3—Dsg2 (1). DSG2 has a signal peptide, four N-terminal extracellular cadherin (EC) repeats, an extracellular anchor, a transmembrane domain, an intracellular anchor, an intracellular cadherin-specific sequence (ICS), a proline-rich linker region (IPL), six intracellular DSG repeat domains, and a DSG terminal domain (DTD) (Figure 4) (2). Classical cadherins typically have five of EC repeats, a single transmembrane domain, and a conserved cytoplasmic domain that interacts with α- and β-catenin and connects a cadherin molecule to the actin cytoskeleton (3). EC repeats are defined by DRE, DXD, and DXNDNXPXF motifs. EC repeats mediate the Ca2+-dependent dimerization of cadherin molecules and the trans-extracellular linkages between cadherin dimers of two neighboring cells. Each EC repeat has four calcium binding motifs that together bind three calcium ions. Calcium binding facilitates linearization and rigidification of the cadherin ectodomain, prevents ectodomain unfolding, and promotes cadherin dimerization and consequent cell-cell adhesion (4-6). The overall 3D structure of the cadherin repeat motif is quite similar to the Greek-key topology of immunoglobulin domains with seven β-strands arranged as two opposing β-sheets with N- and C-termini at the opposite ends (3;5). The overall topology of the extracellular region is that of an elongated, curved structure of tandem EC domains connected by calcium-binding linker regions (7). The intracellular domain of the DSG proteins binds to intermediate filaments via the adaptor proteins desmoplakin and plakoglobin (8). The function of the intracellular anchor sequence in DSG2 is unclear, but that sequence in DSC recruits plakoglobin and desmoplakin to the membrane as well as anchors intermediate filaments (9). The ICS domain mediates interacts between the desmosomal cadherins and catenin family members (e.g., plakoglobin). The region encompassing the IPL, DSG repeat domains, and the DTD is required for strong cell-cell adhesion as well as stabilization of DSG2 at the cell surface through the inhibition of DSG2 internalization (10). The specific functions of the IPL, DSG repeat domains, and DTD are unknown, but the DSG repeat domain putatively regulates homodimerization (11) and the DTD putatively mediates interactions with plakophilins (8). DSG2 is palmitoylated at two cysteines in the juxtamembrane (intracellular anchor) domain (12). DSG2 palmitoylation promotes efficient DSG2 incorporation into junctions and trafficking to the cell surface. The EC1 and EC4 domains undergo N- and O-linked glycosylation, respectively (7). The functional significance of DSG2 glycosylation is unknown; the N-linked glycosylation does not regulate adhesive contacts. The extracellular and intracellular regions of the DSG proteins are targeted by matrix metalloproteinases and cysteine proteases, respectively. ADAM10, ADAM17, and MMP9 promote the shedding of the ectodomain of DSG2 (13-15). In a colonic epithelial cell line, several DSG2 proteolytic products were identified, including a shed extracellular domain, a cell-associated extracellular domain-containing product, and fragments containing the DSG repeat domains and DTD (16). The DSG cleavage products regulate several processes, including apoptosis, tissue homeostasis, and differentiation (16-19). The weg mutation results in substitution of tyrosine 226 for a premature stop codon (Y226*); Tyr226 is within the second EC repeat.
|
Expression/Localization | DSG2 is predominantly expressed in heart, intestine, epidermis, testis and epithelia (simple and complex) (1). DSG2 is also expressed on epithelial precursor cells and on immature hematopoietic progenitor cells from human bone marrow (20). In myeloid lineages, DSG2 is expressed on common myeloid progenitors (CD34+CD45dimCD117+CD33+CD13+) and on pro-myelocytes. DSG2 is also expressed on pro-erythrocytes (CD34+CD45dimCD117+CD71+CD235a−) and B cell lineage progenitors. DSG2 expression progressively decreased as differentiation progressed and was absent on all mature cell types in the bone marrow. DSG2 was also expressed on induced pluripotent stem (iPS) cells. Dsg2 localizes to desmosomes.
|
Background |
Desmosomes are multiprotein complexes that link cadherin to the intermediate filament, providing structural support for tissues that undergo mechanical stress. The desmocollins (DSC1 to DSC3) and DSGs are the adhesion molecules of desmosomes, and are collectively known as desmosomal cadherins. Within desmosomes, the extracellular domains of DSCs and DSGs from neighboring cells form heterophilic interactions in the extracellular space, while intracellularly they are linked to plakoglobin, plakophilins, and desmoplakin (Figure 5). Desmoplakin binds to keratin intermediate filaments, thereby tethering the intermediate filaments to the plasma membrane to physically strengthen the junction. DSG2 has several known functions. (i) DSG2 promotes tight junction integrity in the intestine, which is required for intestinal epithelial barrier integrity (21). (ii) DSG2 regulates intestinal epithelial cell apoptosis during differentiation and inflammation by facilitating the removal of cells after cell-cell adhesion has been compromised (22). Exposure of the epithelium to the cleaved ectodomain of DSG2 resulted in compromised intercellular adhesion, but increased cellular proliferation to promote repair in the inflamed intestine (15). (iii) DSG2 functions in vasculogenic mimicry in melanoma (23). Vasculogenic mimicry is the formation of vascular networks directly by tumor cells, which promotes cancer growth and metastasis. DSG2 regulates tube formation by melanoma cells through promoting cell-cell adhesion, subsequently stabilizing and strengthening vasculogenic mimicry networks (23). (iv) DSG2 functions in cardiomyocyte cohesion and function (24). Mutations in human DSG2 are associated with arrhythmogenic right ventricular dysplasia-10 [ARVD10; OMIM: #610193; (25-27)]. ARVD10 is a myocardial disease characterized by progressive fibrofatty replacement of the cardiac myocytes of the right ventricular wall, resulting in reentrant arrhythmias and sudden death. Mutations in DSG2 have also been linked to cases of dilated cardiomyopathy-1BB [OMIM: #612877; (28)]. DSG2 expression is reduced in the mucosa of patients with Crohn’s disease (29). In contrast, DSG2 is upregulated in several malignancies, including head and neck squamous cell carcinoma (30), prostate cancer (31;32), hepatocellular carcinoma (33), and melanoma (23). DSG2 overexpression predicts poor prognosis in the cancers. In pancreatic adenocarcinoma cells, loss of DSG2 expression results in loss of cell cohesion, increased migration, and invasion (34). Dsg2-deficient mice exhibited embryonic lethality at implantation (35). Dsg2 hypomorph (Dsg2lo/lo) mice expressing reduced amounts of DSG2 were overtly normal, viable, and fertile (20). However, the Dsg2lo/lo mice showed enlarged hearts with fibrotic lesions. The Dsg2lo/lo mice showed greater endothelial cell vascular wall widths compared to control mice. Bone marrow-derived endothelial cells from the Dsg2lo/lo mice showed reduced formation of tube-like structures on Matrigel compared with bone marrow-derived endothelial cells from wild-type mice. Aortic rings from Dsg2lo/lo mice produced significantly fewer vascular sprouts in response to VEGF compared to aortic rings from wild-type mice. Dsg2 mutant mice lacking a portion of the extracellular adhesive domain of DSG2 showed fibrotic lesions in the heart followed by ventricular dilation and premature death (36). Mice expressing a DSG2 mutant with deletion of the extracellular domain showed ventricular dilation, fibrosis, and arrhythmia (37). Conditional villin-Cre DSG2 knockout mice showed increased intestinal permeability, a wider desmosomal space, and alterations in desmosomal and tight junction components (38). Treatment of the conditional knockout mice with DSS resulted in susceptibility to colitis and increased intestinal epithelial barrier disruption (38). Cardiomyocyte-specific Dsg2 knockout mice showed progressive arrhythmogenic cardiomyopathy, chamber dilation, cardiomyocyte necrosis, and interstitial fibrosis (39). Transgenic mice overexpressing mutant DSG2 (Asn271Ser) in the heart showed intracellular space widening at the desomsomes/adherens junctions (intercalated disc), conduction slowing, and reduced sodium current density before cardiomyopathic changes (40).

Putative Mechanism | The intestinal epithelial barrier is maintained by a junctional complex consisting of tight junctions, adherens junctions, and desmosomes. Inflammatory bowel disease is marked by defects in permeability and alterations in junction morphology. DSG2 has known functions in regulating the intestinal epithelial barrier. The phenotype of the weg mice is similar to that of the conditional villin-Cre DSG2 knockout mice (38), suggesting a loss of DSG2-mediated maintenance of tight junction/desmosome integrity of the intestinal epithelial barrier.
