Biological Literature Report of Shedding
Substrate Name Calsyntenin-1(Alc-alpha)
Cell Type
Substrate Description cargo-receptor for the kinesin-1 motor that mediates anterograde transport of APP; may modulate Ca+2-mediated postsynaptic signals.
Substrate Function Category disease;central nervous system (neuron)
Substrate Function Subtype
Sheddase ADAM10, ADAM17
Shedding-related Disease Alzheimer Disease;cell surface protein
Short Summary of Papers small Peptides p3-Alcs were generated via the cleavage of Alcadeins were cleavages by ADAM10/17 and γ-Secretases(regulated intramembrane proteolysis) ; calsyntenin-1 undergoes proteolytically cleaved, and calsyntenin-1 may link extracellular proteolysis in the synaptic cleft and postsynaptic Ca+2 signaling.equentially. the alterations of C termini of p3-Alcs may indicate Alzheimer Disease-related γ-Secretase Dysfunction
Cleavage Information NONE
