DiseaseBreast cancer, lobular (LBC) [MIM:137215]: A type of breast cancer that begins in the milk-producing glands (lobules) of the breast. {ECO:0000269|PubMed:17660459}. Note=The gene represented in this entry may be involved in disease pathogenesis.
DiseaseEndometrial cancer (ENDMC) [MIM:608089]: A malignancy of endometrium, the mucous lining of the uterus. Most endometrial cancers are adenocarcinomas, cancers that begin in cells that make and release mucus and other fluids. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
DiseaseHereditary diffuse gastric cancer (HDGC) [MIM:137215]: A cancer predisposition syndrome with increased susceptibility to diffuse gastric cancer. Diffuse gastric cancer is a malignant disease characterized by poorly differentiated infiltrating lesions resulting in thickening of the stomach. Malignant tumors start in the stomach, can spread to the esophagus or the small intestine, and can extend through the stomach wall to nearby lymph nodes and organs. It also can metastasize to other parts of the body. {ECO:0000269|PubMed:10319582, ECO:0000269|PubMed:12216071}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. Heterozygous CDH1 germline mutations are responsible for familial cases of diffuse gastric cancer. Somatic mutations has also been found in patients with sporadic diffuse gastric cancer and lobular breast cancer.
DiseaseOvarian cancer (OC) [MIM:167000]: The term ovarian cancer defines malignancies originating from ovarian tissue. Although many histologic types of ovarian tumors have been described, epithelial ovarian carcinoma is the most common form. Ovarian cancers are often asymptomatic and the recognized signs and symptoms, even of late-stage disease, are vague. Consequently, most patients are diagnosed with advanced disease. {ECO:0000269|PubMed:8075649}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
DomainThree calcium ions are usually bound at the interface of each cadherin domain and rigidify the connections, imparting a strong curvature to the full-length ectodomain. {ECO:0000269|PubMed:2349235}.
FunctionCadherins are calcium-dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. CDH1 is involved in mechanisms regulating cell-cell adhesions, mobility and proliferation of epithelial cells. Has a potent invasive suppressor role. It is a ligand for integrin alpha-E/beta-7. {ECO:0000269|PubMed:16417575}.
FunctionE-Cad/CTF2 promotes non-amyloidogenic degradation of Abeta precursors. Has a strong inhibitory effect on APP C99 and C83 production. {ECO:0000269|PubMed:16417575}.
InductionExpression is repressed by MACROD1. {ECO:0000269|PubMed:17893710}.

PtmDuring apoptosis or with calcium influx, cleaved by a membrane-bound metalloproteinase (ADAM10), PS1/gamma-secretase and caspase-3 to produce fragments of about 38 kDa (E-CAD/CTF1), 33 kDa (E-CAD/CTF2) and 29 kDa (E-CAD/CTF3), respectively. Processing by the metalloproteinase, induced by calcium influx, causes disruption of cell-cell adhesion and the subsequent release of beta-catenin into the cytoplasm. The residual membrane-tethered cleavage product is rapidly degraded via an intracellular proteolytic pathway. Cleavage by caspase-3 releases the cytoplasmic tail resulting in disintegration of the actin microfilament system. The gamma-secretase-mediated cleavage promotes disassembly of adherens junctions. {ECO:0000269|PubMed:10597309, ECO:0000269|PubMed:11076937, ECO:0000269|PubMed:11953314}.
PtmN-glycosylation at Asn-637 is essential for expression, folding and trafficking. {ECO:0000269|PubMed:18491227}.
PtmUbiquitinated by a SCF complex containing SKP2, which requires prior phosphorylation by CK1/CSNK1A1. Ubiquitinated by CBLL1/HAKAI, requires prior phosphorylation at Tyr-754. {ECO:0000269|PubMed:21283129, ECO:0000269|PubMed:22252131, ECO:0000269|PubMed:22770219}.

SimilarityContains 5 cadherin domains. {ECO:0000255|PROSITE- ProRule:PRU00043}.
Subcellular LocationCell junction. Cell membrane; Single-pass type I membrane protein. Endosome. Golgi apparatus, trans-Golgi network. Note=Colocalizes with DLGAP5 at sites of cell-cell contact in intestinal epithelial cells. Anchored to actin microfilaments through association with alpha-, beta- and gamma- catenin. Sequential proteolysis induced by apoptosis or calcium influx, results in translocation from sites of cell-cell contact to the cytoplasm. Colocalizes with RAB11A endosomes during its transport from the Golgi apparatus to the plasma membrane.
SubunitHomodimer; disulfide-linked. Component of an E-cadherin/ catenin adhesion complex composed of at least E-cadherin/CDH1, beta-catenin/CTNNB1 or gamma-catenin/JUP, and potentially alpha- catenin/CTNNA1; the complex is located to adherens junctions. The stable association of CTNNA1 is controversial as CTNNA1 was shown not to bind to F-actin when assembled in the complex. Alternatively, the CTNNA1-containing complex may be linked to F- actin by other proteins such as LIMA1. Interaction with PSEN1, cleaves CDH1 resulting in the disassociation of cadherin-based adherens junctions (CAJs). Interacts with AJAP1, CTNND1 and DLGAP5 (By similarity). Interacts with TBC1D2. Interacts with LIMA1. Interacts with CAV1. Interacts with the TRPV4 and CTNNB1 complex (By similarity). Interacts with PIP5K1C. Interacts with RAB8B (By similarity). Interacts with RAPGEF2 (By similarity). Interacts with DDR1; this stabilizes CDH1 at the cell surface and inhibits its internalization. {ECO:0000250, ECO:0000269|PubMed:11226248, ECO:0000269|PubMed:12526809, ECO:0000269|PubMed:14595118, ECO:0000269|PubMed:14699157, ECO:0000269|PubMed:16126725, ECO:0000269|PubMed:17261850, ECO:0000269|PubMed:18093941, ECO:0000269|PubMed:19604491, ECO:0000269|PubMed:20116244, ECO:0000269|PubMed:20432435, ECO:0000269|PubMed:7982500}.
