Journal ArticleDOI
Stomatin, flotillin-1, and flotillin-2 are major integral proteins of erythrocyte lipid rafts.
Ulrich Salzer,Rainer Prohaska +1 more
TL;DR: Stomatin and the flotillins are present as independently organized high-order oligomers, suggesting that these complexes act as separate scaffolding components at the cytoplasmic face of erythrocyte lipid rafts.
Journal ArticleDOI
Association of stomatin with lipid bodies.
Ellen Umlauf,Edina Csaszar,Manuel Moertelmaier,Gerhard J. Schuetz,Robert G. Parton,Rainer Prohaska +5 more
TL;DR: The data suggest that LBs are not only involved in the storage of lipids but also participate actively in the cellular signaling network and the homeostasis oflipids.
Journal ArticleDOI
Erythrocyte Glut1 Triggers Dehydroascorbic Acid Uptake in Mammals Unable to Synthesize Vitamin C
Amélie Montel-Hagen,Sandrina Kinet,Nicolas Manel,Cédric Mongellaz,Rainer Prohaska,Jean-Luc Battini,Jean Delaunay,Marc Sitbon,Naomi Taylor +8 more
TL;DR: It is reported that glucose transport actually decreases during human erythropoiesis despite a >3-log increase in Glut1 transcripts, and stomatin, an integral erythrocyte membrane protein, is identified as regulating the switch from glucose to DHA transport.
Journal ArticleDOI
Flotillin-1/reggie-2 traffics to surface raft domains via a novel golgi-independent pathway. Identification of a novel membrane targeting domain and a role for palmitoylation.
Isabel C. Morrow,Shane L. Rea,Sally Martin,Ian A. Prior,Rainer Prohaska,John F. Hancock,David E. James,Robert G. Parton +7 more
TL;DR: It is shown that newly synthesized flotillin-1 reaches the plasma membrane via a Sar1-independent and brefeldin A-resistant targeting pathway, involving a Golgi-independent trafficking pathway, the PHB domain, and palmitoylation.
Journal ArticleDOI
Erythrocyte detergent-resistant membrane proteins: Their characterization and selective uptake during malarial infection
Sean C. Murphy,Benjamin U. Samuel,Travis Harrison,Kaye D. Speicher,David W. Speicher,Marion E. Reid,Rainer Prohaska,Philip S. Low,Michael J. A. Tanner,Narla Mohandas,Kasturi Haldar +10 more
TL;DR: Ten internalized DRM proteins show varied lipid and peptidic anchors indicating that, contrary to the prevailing model of apicomplexan vacuole formation, DRM association, rather than lipid anchors, provides the preferred criteria for protein recruitment to the malarial vacuoles.
