Identification of novel substrates for Intramembrane Proteases

 

Together with the Chair for Neuroproteomics at the German Center for Neurodegenerative Diseases, DZNE, and at the Technical University of Munich, the Chair for Biochemistry and Molecular Biology aims to identify new substrates for intramembrane proteases and to determine the cleavage sites within these substrates.
With help of modern mass spectrometry, we significantly expanded the range of known substrates for both the SPPL3 and the SPPL2c protease.
