Kassem Ghaddar was supported by the FNRS to attend a high-interest “Benzon meeting” about “Membrane proteins: structure, function and dynamics” held on August 19-22 in Copenhagen.

The story is that Albert II scheduled a visit of the town of Charleroi, and at this occasion he came to the Biopark of Gosselies, where he wished to visit a lab and meet scientists. Why our lab was selected for this visit remains a mystery … Anyway, after having been introduced to all members of the lab, the King examined yeast cells under the microscope (“they look like eggs” he said). Then Anna Maria Marini and Sophie Biver presented the work carried out about the role of Rhesus proteins as ammonium transporters. Certainly a big honor and a great souvenir for us …
Abdoulaye Barry, who joined the lab last November after his PhD thesis in Marseille, was informed by the FNRS he got a three-year postdoc grant as “Chargé de Recherche”. He couldn’t get better news indeed, congratulations to him! The research work of Abdoulaye deals with the ubiquitylation and intracellular traffic of amino acid transporters, in yeast and human cells.
Elie’s research work deals with the mechanisms stimulating the ubiquitylation and endocytosis of amino acid transporters. In 1983, Marcelle Grenson published her famous paper describing the “inactivation” by ammonium of the yeast Gap1 permease, and the isolation of a mut2 mutant in which this inactivation is defective [1]. Later studies [2] showed that the mut2 mutation (also named npi1) alters the RSP5 gene encoding the HECT-type ubiquitin ligase enzyme [3] responsible for the ubiquitylation of all thus far reported plasma membrane proteins of yeast, including Gap1 [4].
Marcelle Grenson The “Solvay Award” is awarded annually by the Solvay group to 2nd and 3rd cycle students who have realized a high-quality work within the Faculty of Science or the Faculty of Applied Sciences of ULB or VUB. This year one of the 3rd cycle awards was attributed to our former PhD student Elisa Llinares for her research work on the yeast Ypq membrane transporters of the yeast S. cerevisiae. Elisa is now employee of Bone therapeutics, a spin-off company of ULB. Congratulations to Elisa for this award ! We have participated and contributed to the “Membrane transport proteins” meeting organized by our colleague François Chaumont in Louvain-la-Neuve (April 26th) with the help of the Belgian Society of Biochemistry and Molecular Biology. We have attended the “Model Organisms” conference organized by NARC in Namur on April 19th. The speakers included Pr. Paul Nurse, who received the Nobel prize in 2011 for his work on cell division control (CDC) genes in yeast. |
