CC -!- FUNCTION: Inhibits amyloid precursor protein processing, probably by
CC blocking BACE1 activity (By similarity). Enhances trafficking of the
CC glutamate transporter SLC1A1/EAAC1 from the endoplasmic reticulum to
CC the cell surface (By similarity). Plays a role in the translocation of
CC SLC2A4/GLUT4 from intracellular membranes to the cell membrane which
CC facilitates the uptake of glucose into the cell (By similarity).
