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 ...

Endoplasmic Reticulum Export of GPI-Anchored Proteins
(MDPI, 2019)
Protein export from the endoplasmic reticulum (ER) is an essential process in all eukaryotes driven by the cytosolic coat complex COPII, which forms vesicles at ER exit sites for transport of correctly assembled secretory ...

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 ...

Osh proteins regulate COPII-mediated vesicular transport of ceramide from the endoplasmic reticulum in budding yeast
(Company of Biologists Ltd, 2014)
Lipids synthesized at the endoplasmic reticulum (ER) are delivered to the Golgi by vesicular and non-vesicular pathways. ER-to-Golgi transport is crucial for maintaining the different membrane lipid composition and identities ...

Análisis funcional de mecanismos de selección molecular que operan en la ruta secretora temprana
(2013-12-20)
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 la ruta, ...

Análisis funcional del complejo p24 en Saccharomyces cerevisiae
(2010)
El propósito general de esta tesis es el análisis molecular de la función del complejo p24 en los procesos selectivos de transporte vesicular entre el RE y el aparato de Golgi en la levadura Saccharomyces cerevisiae. ... ...

Papel de los receptores de carga en la organización funcional de la ruta secretora temprana
(2016-10-07)
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, ...

Limited ER quality control for GPI-anchored proteins
(Rockefeller University Press, 2016)
Endoplasmic reticulum (ER) quality control mechanisms target terminally misfolded proteins for ER-associated degradation (ERAD). Misfolded glycophosphatidylinositol-anchored proteins (GPI-APs) are, however, generally poor ...
