Illustration of a cell that has a healthy part and a sick part. In the healthy part, there is a network of protein-protein interactions between different human proteins. In the diseased part, which has been infected by a virus, the network of human protein-protein interactions is destroyed because certain network proteins bind to viral proteins instead. This causes the cell to start producing virus particles that are released from the cell.

Molecular interactions in cell function and dysfunction

We focus on interactions between linear motifs and peptide binding domains and aim to contribute with novel insights into the human protein-protein interaction networks in health and diseases. In addition, we explore the interplay between protein-protein and protein-phospholipid interactions. Our research is interdisciplinary and combines biochemical and biophysical methods with bioinformatics and cell-based assays.
