GRASP55 regulates intra-Golgi localization of glycosylation enzymes to control glycosphingolipid biosynthesis

Giovanni D'Angelo, Charlotte Julie Caroline Gehin, Laura Capolupo, Riccardo Rizzo

The Golgi apparatus, the main glycosylation station of the cell, consists of a stack of discontinuous cisternae. Glycosylation enzymes are usually concentrated in one or two specific cisternae along the cis-trans axis of the organelle. How such compartment ...

BET1 variants establish impaired vesicular transport as a cause for muscular dystrophy with epilepsy

Matteo Dal Peraro, Mykola Dergai, Ying Hu

BET1 is required, together with its SNARE complex partners GOSR2, SEC22b, and Syntaxin-5 for fusion of endoplasmic reticulum-derived vesicles with the ER-Golgi intermediate compartment (ERGIC) and the cis-Golgi. Here, we report three individuals, from two ...

Characterization of Protein-Membrane Interfaces through a Synergistic Computational-Experimental Approach

Alessio Prunotto

The characterization of biological interfaces is widely recognized as one of the main challenges for modern biology. In particular, biological membranes are nowadays known to be an active environment that allows membrane proteins to perform their work and ...

An overview of cellular ultrastructure in benthic foraminifera: New observations of rotalid species in the context of existing literature

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

We report systematic transmission electron microscope (TEM) observations of the cellular ultrastructure of selected, small rotalid benthic foraminifera. Nine species from different environments (intertidal mudflat, fjord, and basin) were investigated: Ammo ...

, ,

Sphingolipids are membrane lipids globally required for eukaryotic life. The sphingolipid content varies among endomembranes with pre- and post-Golgi compartments being poor and rich in sphingolipids, respectively. Due to this different sphingolipid conten ...

GOLPH3 and oncogenesis: What is the molecular link?

Riccardo Rizzo

The Golgi phosphoprotein 3 (GOLPH3) is encoded by a gene that is located in a region of the human genome that is often amplified in different solid tumours. GOLPH3, an evolutionary conserved phosphatidylinositol 4-phosphate (PI4P) binding protein, is mainl ...

2016

Newly synthesized proteins and lipids are transported across the Golgi complex via different mechanisms whose respective roles are not completely clear. We previously identified a non-vesicular intra-Golgi transport pathway for glucosylceramide (GlcCer)--t ...
