Drosophila LKB1 is required for the assembly of the polarized actin structure that allows spermatid individualization.

Autor: Jean-Louis Couderc, Graziella Richard, Caroline Vachias, Vincent Mirouse

Publikováno v: PLoS ONE, Vol 12, Iss 8, p e0182279 (2017)

In mammals, a testis-specific isoform of the protein kinase LKB1 is required for spermiogenesis, but its exact function and specificity are not known. Human LKB1 rescues the functions of Drosophila Lkb1 essential for viability, but these males are st

Gap junction-dependent amino acid transfer promotes germ cell growth

Autor: Caroline Vachias, Camille Tourlonias, Louis Grelée, Nathalie Gueguen, Yoan Renaud, Parvathy Venugopal, Graziella Richard, Pierre Pouchin, Émilie Brasset, Vincent Mirouse

Gap junctions allow the exchange of small molecules between cells. How this function could be used to promote cell growth has never been explored. DuringDrosophilaovarian follicle development, germ cells, which are surrounded by epithelial somatic ce

Basement membrane diversification relies on two competitive secretory routes defined by Rab10 and Rab8 and modulated by dystrophin and the exocyst complex

Autor: Cynthia Dennis, Pierre Pouchin, Graziella Richard, Vincent Mirouse

The basement membrane (BM) is an essential structural element of tissues, and its diversification participates in organ morphogenesis. However, the traffic routes associated with BM formation and the mechanistic modulations explaining its diversifica

Background : Scaffold proteins support a variety of key processes during animal development. Mutant mouse for the MAGUK protein Discs large 5 (Dlg5) presents a general growth impairment and moderate morphogenetic defects. Results : Here, we generated

Bacteriophage T4 polynucleotide kinase triggers degradation of mRNAs

Autor: Marc Uzan, Sylvain Durand, Graziella Richard, François Bontems

Publikováno v: Proceedings of the National Academy of Sciences of the United States of America
Proceedings of the National Academy of Sciences of the United States of America, National Academy of Sciences, 2012, 109 (18), pp.7073-8. ⟨10.1073/pnas.1119802109⟩

International audience; The bacteriophage T4-encoded RegB endoribonuclease is produced during the early stage of phage development and targets mostly (but not exclusively) the Shine-Dalgarno sequences of early genes. In this work, we show that the de

International audience; The T4 RegB endoribonuclease cleaves specifically in the middle of the -GGAG- sequence, leading to inactivation and degradation of early phage mRNAs. In vitro, RegB activity is very weak but can be enhanced 10- to 100-fold by
