Research Focus

Project description: The molecular mechanism of human peroxisomal protein import

Peroxisomes are membrane-enclosed organelles found in almost all eukaryotic cells. Their vital biosynthetic functions are maintained by PEX proteins which transport necessary enzymes across the membrane into peroxisomes via a yet unknown mechanism. In the Sattler lab, we seek to get insights into the structure and function of the import pore formed via liquid-liquid phase separation in the peroxisomal membrane. Advanced biochemical and biophysical techniques are employed to recombinantly produce the human pore components PEX5, PEX13 and PEX14 and investigate these proteins in model membranes and under phase-separated conditions in vitro using light/fluorescence microscopy. The Amgen scholar will be involved in designing (cloning) and optimizing (purification) different protein constructs followed by screening LLPS conditions using microscopy and biochemical characterization, ie protein-protein interactions, using nuclear magnetic resonance (NMR) spectroscopy, electron microscopy (EM) and other biophysical techniques (ITC, SLS), which will ultimately provide foundation to obtain a structural model of the peroxisomal protein import machinery.
