| MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an adhesive junction associated protein of the armadillo/beta-catenin superfamily and is implicated in brain and eye development and cancer formation. The protein encoded by this gene promotes the disruption of E-cadherin based adherens junction to favor cell spreading upon stimulation by hepatocyte growth factor. This gene is overexpressed in prostate adenocarcinomas and is associated with decreased expression of tumor suppressor E-cadherin in this tissue. This gene resides in a region of the short arm of chromosome 5 that is deleted in Cri du Chat syndrome. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2013]
PHENOTYPE: Mice homozygous for a reporter allele exhibit abnormal conditioning, spatial learning and coordination behaviors and abnormal long term potentiation. [provided by MGI curators]

| Protein Function and Prediction |
Ctnnd2 (alternatively, δ-catenin) is a member of the beta-catenin superfamily and modulates neurite outgrowth and synaptic activity (1). Ctnnd2 links to the actin cytoskeleton through a repeating central armadillo domain to promote cell adhesion (2;3).
|
| Expression/Localization |
Northern blot analysis of human tissues identified CTNND2 in human fetal brain (1). In adult neural tissues, δ-catenin is expressed in the dendrites, is enriched in the postsynaptic density (4). Western blot analysis of mouse tissues identified Ctnnd2 in skeletal muscle and pancreas (1).
|
| Background |
Mutations in CTNND2 can cause mental retardation in cri-du-chat syndrome [OMIM #123450; (5)], a condition in which young children have microcephaly, round face, hypertelorism, micrognathia, epicanthal folds, low-set ears, hypotonia, and severe psychomotor and mental retardation. One of the most characteristic features in newborns is a high-pitched cat-like cry that is usually considered diagnostic for the syndrome. Polymorphisms in CTNND2 have also been linked to myopia (6-8).
