#Unit 4. Cell Communication and Cell Signaling

Binding of insulin to its receptor triggers activation of a protease that catalyzes a site-specific endoproteolytic cleavage of TUG

#Unit 4. Cell Communication and Cell Signaling

Released N-terminal TUG fragment bind to the kinesin, initiates the microtubule-based movement of the GSVs to the plasma membrane.
