Vesicle formation depends on an extensive network of interacting proteins that form large, dynamic modules to drive membrane budding. Recent studies have identified a distinct subfamily of P-type ATPases as putative phospholipid transporters that interact and cooperate with cytosolic coat proteins to drive vesicle formation at the trans-Golgi network, endosomal compartment and plasma membrane. The project aims to determine the mechanism by which these P-type ATPases function in vesicle biogenesis. Components of the P-type ATPase-coupled module will be reconstituted into giant liposomes to study their activities. The spatiotemporal localization of P4 ATPases and endocytic proteins will be analyzed in vivo by live-cell microscopy.
