At1g56590(AP-3micro) positively regulates the abscisic acid responses independently of AGB1 in seed germination, while AP-3micro does require AGB1 to regulate abscisic acid responses during post-germination growth.
Title: The Arabidopsis adaptor protein AP-3? interacts with the G-protein ? subunit AGB1 and is involved in abscisic acid regulation of germination and post-germination development.

zip4 is a loss-of-function mutant of a putative ortholog of the yeast AP-3 mu subunit, and is involved in protein trafficking between the trans-Golgi network and vacuoles.
Title: ZIP genes encode proteins involved in membrane trafficking of the TGN-PVC/vacuoles.
