General annotation (Comments)
| Function | Calcium-dependent cell-adhesion protein By similarity. May play a role in activity-induced synaptic reorganization underlying long term memory By similarity. Could be involved in CDH2 internalization through TAOK2/p38 MAPK pathway. In hippocampal neurons, may play a role in the down-regulation of dendritic spines, maybe through its action on CDH2 endocytosis By similarity. |
| Subunit structure | The N-terminal extracellular domain forms homophilic interactions; these interactions activate p38 MAPK via TAOK2 and trigger endocytosis By similarity. Interacts with CDH2; this interaction may lead to CDH2 cointernalization By similarity. Interacts with CDH11 By similarity. Interacts with TAOK2 By similarity. |
| Subcellular location | Cell membrane; Single-pass type I membrane protein By similarity. Cell projection › dendrite By similarity. Cell junction › synapse › presynaptic cell membrane. Cell junction › synapse › postsynaptic cell membrane. Note: Also expressed in neuronal cell bodies By similarity. Localized to excitatory, but not with inhibitory, synapses By similarity. |
| Sequence similarities | Contains 6 cadherin domains. |
