Welcome to the Functional Protein Analysis group

Besides the understanding which proteins are expressed in a certain tissue to a defined time point, the characterization of interactions in a cell is essential for a detailed description of complex biological systems. Cells respond along defined pathways to external stimuli. This can result in cell division, in the formation of tissues but also in the development of diseases. Signals are transmitted by specific interactions and can result in a changed expression level of proteins. A key role in the responds is the regulation of those genes by transcription factors and the activation of specific DNA binding proteins. Protein Microarrays are a powerful tool to analysis signalling pathways, studying the dynamic of protein phosphorylation or characterize the antibody repertoire in sera. Overall protein microarrays are a technology that has substantial impact on our understanding of cellular processes.
