Our research network met again, this time at the “Haus der Universität” in Düsseldorf. The focus of this meeting was to foster collaborations and initiate new projects. As local guest speaker we had Prof. Heiner Schaal (Institute of Virology, HHUD) with a very entertaining talk on alternative splicing. Thanks to Michael Feldbrügge and his team for having us…

The group of Fulvia Bono published a structure-to-functional analysis of the bicoid mRNA-localization factor Exuperantia (Exu) from Drosophila. Their crystal structure shows that Exu forms a dimer and that each subunit consists of a catalytically inactive 3’-5’ EXO domain and a SAM domain. Both domains are required for binding to a highly structured region in the 3’UTR of the bicoid transcript. Thus, Exu is a non-canonical RNA-binding protein.

The group of Anne Ephrussi used a very different approach to study mRNA localization in the fruit fly. In this study, all RNA-interacting proteins were mapped before and after maternal-to-zygotic transition of early embryogenesis. From the over 500 detected factors about half of them had not been described before as RNA-binding proteins. Furthermore the comparison of both datasets indicates that the RNA-bound proteome is highly dynamic during early developmental stages.

Our first meeting of the DFG Research Unit 2333 (FOR2333) took place on March 1st and 2nd in the guesthouse of the University Tübingen in Blaubeuren. We enjoyed our first get-together with excellent discussions and talks. Looking forward to our next meeting taking place in Düsseldorf on September 5th to 7th, again focusing on ‘macromolecular complexes in mRNA localization’…
