Amna Asif-Laidin, 34, is a post-doctoral fellow in Pascale Lesage et Emmanuelle Fabre team « Genome Biology: From mobile DNA to chromosome dynamics » at the Institut de Recherche Saint-Louis, Paris (Inserm U944, CNRS/Paris Univ UMR7212). During her PhD, carried out under the supervision of Laure Teysset at the Institut of Biology Paris-Seine, she was mainly interested in the repression of transposable elements, by small non-coding RNAs, in the Drosophila germ line. Her post-doctoral work aims at deciphering the molecular bases of Ty1 retrotransposon integration selectivity in the genome of the yeast Saccharomyces cerevisiae. A previous publication described the key role played by the interaction between Ty1 integrase and the AC40 subunit of RNA polymerase III (Pol III) in Ty1 integration preference upstream of Pol III-transcribed genes. In the selected publication, Amna Asif-Laidin and co-workers have identified six consecutive amino acids of Ty1 integrase that are necessary for the interaction with AC40 and shown that this short domain allows the recruitment of Ty1 integrase to all the genes transcribed by Pol I and Pol III because AC40 is common to both polymerases. However, Ty1 integration only occurs at Pol III-transcribed genes, suggesting the intervention of additional factors (chromatin or Pol III specific co-factors) in Ty1 integration selectivity. The study also shows how this short amino acid sequence is sufficient to redirect integration of a chimeric retrotransposon to Pol III‐transcribed genes.
