How to deal with missing values in proteomics data

How to deal with missing values in proteomics data

Missing values prevent the feasibility of methods for analysis, can cause bias, and may negatively impact statistical power. We developed the concept of data-driven selection of an imputation algorithm (DIMA) which optimally selects an imputation method for a given proteomics data set.

Structural model of the peroxisomal docking complex

Structural model of the peroxisomal docking complex

Our paper on the peroxisomal receptor docking complex is online! In collaboration with the Gatsogiannis lab at MPI Dortmund and the Erdmann lab from Ruhr University in Bochum using an integrative approach we were able to derive the first structural model of the challenging peroxisomal docking complex Pex14/Pex17.

Regulation of the transport of citrate synthase into peroxisomes

Regulation of the transport of citrate synthase into peroxisomes

In close collaboration with the Schuldiner lab from the Weizmann Institute, Israel, and the Erdmann lab from the Ruhr University Bochum, Germany, Renate Maier and Andreas Schummer revealed that phosphorylation of Pex14, a core component of the peroxisomal import machinery, provides a posttranslational mechanism to redistribute peroxisomal citrate synthase Cit2 to the cytosol. This helps yeast cells to rapidly adjust their metabolism to the available carbon source.

Nano-switches in the cell

Nano-switches in the cell

In a joint study conducted by Ida Suppanz and coworkers in Bettina Warscheid's lab with the group of Agnieszka Chacinska from the Centre of New Technologies in Warsaw a new mechanism was discovered that enables mitochondria with impaired redox balance to regulate the synthesis of new proteins in the cytoplasm. The results were published in the current issue of "Nature Communications".

Discovering, counting, cataloguing proteins

Discovering, counting, cataloguing proteins

Imagine a complex technical system, like a car engine. Unbelievable to have hundreds of parts you don't know the function or exact place of. Within eukaryotic cells, however, still many hundreds of proteins have unknown functions and localisation. In a study that is part of Marcel Morgenstern's PhD thesis 82 new mitochondrial proteins were discovered by quantitative mass spectrometry and biochemical methods in the eukaryotic model organism baker's yeast. For an additional 119 proteins their mitochonrial localisation had been ambiguous. Mitochondria are small organelles within the cell that have about the size of a bacterium and are known as the cell's power plant. Furthermore, they fulfill numerous vital processes and are associated with many human diseases caused by cellular defects. The study was conducted together with a team of scientists from the universities of Freiburg, Homburg, and Rehovot (Israel) and was published in the current issue of Cell Reports.
