Introducción La organización estructural y funcional de la célula eucariota depende, en gran medida, de la actividad de la ruta secretora. Los procesos selectivos de transporte vesicular que operan a lo largo de esta ruta, aseguran la llegada de las distintas proteínas y lípidos a sus destinos funcionales adecuados. De esta forma, se mantiene...

Understanding how in eukaryotic cells thousands of proteins are sorted from each other through the secretory pathway and delivered to their correct destinations is a central issue of cell biology. We have further investigated in yeast how two distinct types of cargo proteins are sorted into different endoplasmic reticulum (ER) exit sites (ERES)...

In eukaryotic cells, a subset of cell surface proteins is attached by the glycolipid glycosylphosphatidylinositol (GPI) to the external leaflet of the plasma membrane where they play important roles as enzymes, receptors, or adhesion molecules. Here we present a protocol for purification and mass spectrometry analysis of the lipid moiety of...
