#XL - T Zoology

In resting cells, the majority of the GLUT4 protein is

localized to specialized GLUT4 storage vesicles (GSVs)

#XL - T Zoology

GSVs tethered to the Golgi matrix, by a protein termed TUG (Tether containing a UBX domain for GLUT4).

#XL - T Zoology

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

#XL - T Zoology

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

#XL - T Zoology

Movement of the GSVs to the plasma membrane is regulated by two monomeric GTP-binding proteins -RalA and Rab10
