Determination of the lipid composition of the GPI anchor
(PLOS, 2021)
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, ...

Trafficking of glycosylphosphatidylinositol anchored proteins from the endoplasmic reticulum to the cell surface
(Elsevier, 2016)
In eukaryotes, many cell surface proteins are attached to the plasma membrane via a glycolipid glycosylphosphatidylinositol (GPI) anchor. GPI-anchored proteins (GPI-APs) receive the GPI anchor as a conserved posttranslational ...

Activation of the unfolded protein response pathway causes ceramide accumulation in yeast and INS-1E insulinoma cells
(Elsevier, 2012)
Sphingolipids are not only important components of membranes but also have functions in protein trafficking and intracellular signaling. The LCB1 gene encodes a subunit of the serine palmitoyltransferase, which is responsible ...

The Emp24 complex recruits a specific cargo molecule into endoplasmic reticulum-derived vesicles
(Rockefeller University Press, 2000)
Members of the yeast p24 family, including Emp24p and Erv25p, form a heteromeric complex re- quired for the efficient transport of selected proteins from the endoplasmic reticulum (ER) to the Golgi ap- paratus. The ...

The yeast p24 complex regulates gpi-anchored protein Transport and quality control by monitoring anchor remodeling
(American Society for Cell Biology, 2011)
Glycosylphosphatidylinositol (GPI)-anchored proteins are secretory proteins that are attached to the cell surface of eukaryotic cells by a glycolipid moiety. Once GPI anchoring has occurred in the lumen of the endoplasmic ...

The yeast p24 complex is required for the formation of COPI retrograde transport vesicles from the Golgi apparatus
(Rockefeller University Press, 2008)
The p24 family members are transmembrane proteins assembled into heteromeric complexes that continuously cycle between the ER and the Golgi apparatus. These cargo proteins were assumed to play a structural role in COPI ...
