Biological Literature Report of Shedding
Substrate Name Sodium channel subunit beta 4 (Scn4b)
Cell Type
Substrate Description assembly, expression, and functional modulation of the heterotrimeric complex of the sodium channel;required to reconstitute full properties of the native sodium channel
Substrate Function Category growth factor & growth hormone
Substrate Function Subtype
Sheddase BACE1 (memapsin-2)
Shedding-related Disease ion channel
Short Summary of Papers β subunits of voltage-gated sodium channels are processed by BACE1 and γ-secretase (regulated intramembrane proteolysis) sequentially; shed ectodomain may be required for β subunit-mediated neurite outgrowth
