Protein Information
Synonyms CAPR
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).
Cellular Location Cytoplasm. Cytoplasm, cytoskeleton. Cell junction, adherens junction. Cell membrane; Peripheral membrane protein; Cytoplasmic side Cell projection, axon. Note=Recruited to the nucleus upon ZNF639 overexpression

It has been shown that alpha N-catenin, a linker between cadherin adhesion receptors and the actin cytoskeleton, is essential for stabilizing dendritic spines in rodent hippocampal neurons in culture. Results suggest that alpha N-catenin is a key regulator for the stability of synaptic contacts (1). We show here that antibodies against alpha catenin also immunoprecipitate complexes that contain human N-cadherin, mouse P-cadherin, chicken A-CAM (adherens junction-specific CAM; also called N-cadherin) or Xenopus U-cadherin, demonstrating that alpha catenin is complexed with other cadherins (2).
