Internalization and trafficking of fluorescent-labeled phospholipids in yeast.
Phospholipid reporter molecules, containing a fluorescent group attached to a short, acyl chain, spontaneously insert into the plasma membrane of yeast cells allowing retrograde trafficking to intracellular organelles as well as their metabolic fates to be monitored. This approach provides the framework for determining the dependence of particular phospholipid trafficking and metabolic steps on a wide range of genes known to be required for related membrane transport functions as well as for developing genetic screens to identify novel genes required for these processes. This review presents an overview of insights gained into phospholipid trafficking and metabolism using this approach.
