Abstract
Atg8-interacting proteins (ATI1 and ATI2) are unique to plants. Under conditions of carbon starvation, ATI1 and ATI2 become associated with spherical compartments that dynamically move along the ER network [ 1 ]. ATI1 is also located on bodies associating with plastids, and it seems to be involved in autophagic plastid-to-vacuole trafficking through its ability to interact with both plastid proteins and ATG8 [ 2 ].
1. A new type of compartment, defined by plant-specific Atg8-interacting proteins, is induced upon exposure of Arabidopsis plants to carbon starvation. Plant Cell 24, 288-303
2. Arabidopsis ATG8-INTERACTING PROTEIN1 is involved in autophagy-dependent vesicular trafficking of plastid proteins to the vacuole. Plant Cell 26, 4084-101
