Yck3 casein kinase-mediated phosphorylation determines Ivy1 localization and function at endosomes and vacuole

News, Publications / , , / By /

Sophie Grziwa, Jan-Hannes Schäfer, Raffaele Nicastro, Annabel Arens, Claudio De Virgilio, Florian Fröhlich, Arne Moeller, Jieqiong Gao, Lars Langemeyer, Christian Ungermann The casein kinase Yck3 is a central regulator at the vacuole that phosphorylates several proteins involved in membrane trafficking. Here, we set out to identify novel substrates. We localized endogenously tagged Yck3 not only …

Structure of the metazoan Rab7 GEF complex Mon1–Ccz1–Bulli

News, Publications / , , / By /

Eric Herrmann, Jan-Hannes Schäfer, Stephan Wilmes, Christian Ungermann, Arne Moeller, and Daniel Kümmel The endosomal system of eukaryotic cells represents a central sorting and recycling compartment linked to metabolic signaling and the regulation of cell growth. Tightly controlled activation of Rab GTPases is required to establish the different domains of endosomes and lysosomes. In metazoans, …
