Calsyntenins (calsyntenin-1, -2, -3) compose a family of neuronally expressed proteins that belong to the cadherin superfamily of cell adhesion molecules (PMID: 24966372; 12498782). Calsyntenin-1 (CLSTN1) is a proteolytically processed postsynaptic membrane protein with a cytoplasmic calcium-binding domain. By binding Ca2+, calsyntenin-1 may modulate Ca2+-mediated postsynaptic signals (PMID: 11161476). Calsyntenin-1 is a transmembrane cargo-docking protein for Kinesin-1-mediated vesicular transport (PMID: 16760430). It can mediate axonal transport of the amyloid precursor protein and regulate Aβ production
