In a longstanding cooperation with Prof. Dr. Bernd Schröder from the Institute of Physiological Chemistry at the Technical University of Dresden, the Chair for Biochemistry and Molecular Biology is investigating the physiological function of SPP / SPPL proteases. The collaboration particularly enables the efficient use of various model systems.
In a recent study, we were able to show that SPPL2c, a representative of the GxGD aspartyl proteases, impacts on the vesicular transport in cells and is involved in the efficient maturation of male germ cells.
