Abstract

Background: The machinery for interorganelle phosphatidylserine (PtdSer) transport is poorly defined at the molecular level.

Results: Molecular interaction studies identify specific protein-protein and protein-lipid interactions in PtdSer transport.

Conclusion: A protein and lipid interaction network defines key participants in PS transport to the locus of PtdSer-decarboxylase 2.

Significance: This study identifies important molecular participants involved in non-vesicular phospholipid traffic.
