ADP-ribosylation factor-like protein 6-interacting protein 1 (ARL6IP1)

Positively regulates SLC1A1/EAAC1-mediated glutamate transport by increasing its affinity for glutamate at a PKC activity-dependent manner. Promotes the catalytic efficiency of SLC1A1/EAAC1 likely by decreasing its interaction with ARL6IP5, a negative regulator of SLC1A1/EAAC1-mediated glutamate transport (By similarity).

Plays a role in the formation and stabilization of endoplasmic reticulum tubules (PubMed:24262037). Negatively regulates apoptosis, possibly by regulating the action of caspase-9 (CASP9).
