General annotation (Comments)
| Function | May function as a linker between cadherin adhesion receptors and the cytoskeleton to regulate cell-cell adhesion and differentiation in the nervous system. Regulates morphological plasticity of synapses and cerebellar and hippocampal lamination during development. Functions in the control of startle modulation By similarity. |
| Subunit structure | Interacts with ZNF639. Ref.8 |
| Subcellular location | Cytoplasm. Cytoplasm › cytoskeleton By similarity. Cell junction › adherens junction By similarity. Cell membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Cell projection › axon By similarity. Note: Recruited to the nucleus upon ZNF639 overexpression. Ref.8 |
| Sequence similarities | Belongs to the vinculin/alpha-catenin family. |
