Meioc-Piwil1 complexes regulate rRNA transcription for differentiation of spermatogonial stem cells

Toshihiro Kawasaki, Toshiya Nishimura, Naoki Tani, Carina Ramos, Emil Karaulanov, Minori Shinya, Kenji Saito, Emily Taylor, René F. Ketting, Kei‐ichiro Ishiguro, Minoru Tanaka, Kellee Renee Siegfried, Noriyoshi Sakai

The paper shows that Meioc-Piwil1 complexes regulate rRNA transcription in zebrafish spermatogonial stem cells, preventing Piwil1 from localizing to nucleoli and promoting differentiation.

piRNA processing by a trimeric Schlafen-domain nuclease

Nadezda Podvalnaya, Alfred W. Bronkhorst, Raffael Lichtenberger, Svenja Hellmann, Emily Nischwitz, Torben Falk, Emil Karaulanov, Falk Butter, Sebastian Falk, René F. Ketting

The paper identifies PUCH, a trimeric Schlafen-domain nuclease that initiates piRNA processing in C. elegans by cleaving 5-end piRNA precursors, revealing a novel RNA endonuclease mechanism.

The Caenorhabditis elegans TDRD5/7-like protein, LOTR-1, interacts with the helicase ZNFX-1 to balance epigenetic signals in the germline

Elisabeth A. Marnik, Miguel Vasconcelos Almeida, Patricia Giselle Cipriani, George Chung, Edoardo Caspani, Emil Karaulanov, Hin Hark Gan, John Zinno, Ida J. Isolehto, Fridolin Kielisch, Falk Butter, Catherine S. Sharp, Roisin M. Flanagan, Frederic X. Bonnet, Fabio Piano, , Dustin L. Updike

The paper identifies LOTR-1, a C. elegans protein with LOTUS and Tudor domains, which interacts with ZNFX-1 to regulate small RNA processing in the germline.

GTSF-1 is required for the formation of a functional RNA-dependent RNA Polymerase complex in C. elegans

Miguel Vasconcelos Almeida, Sabrina Dietz, Stefan Redl, Emil Karaulanov, Andrea Hildebrandt, Christian Renz, Helle D. Ulrich, Julian König, Falk Butter, René F. Ketting

The paper identifies GTSF-1 as a protein required for the formation of an RNA-dependent RNA Polymerase complex in C. elegans, which is essential for 26G-RNA generation.
