SPECS: Secretome protein enrichment with click sugars (Kuhn et al. EMBO J 2012).
The secretome comprises all proteins secreted or proteolytically released from cells. A systematic analysis of the secretome has previously been difficult due to technical constraints and mostly required serum-free and even protein-free media. SPECS solves these limitations and allows secretome analyses under (patho)physiological conditions and from primary cells. SPECS comprises metabolic labelling of cellular glycoproteins with artificial (azido) sugars followed by click chemistry-mediated biotinylation of cellular, but not of serum glycoproteins. The click-chemistry reaction is the bioorthogonal reaction of an azide moiety with a cycloalkyne. We use the biotinylated, strained cycloalkyne dibenzylcyclooctyne (DBCO-PEG12-biotin) and tetraacetyl-N-azidoacetyl-mannosamine (ManNAz). ManNAz is only incorporated into the newly synthesized cell-derived proteins, but not into serum proteins. After biotinylation this allows streptavidin-mediated purification of cell-derived proteins, but not of the unlabelled serum proteins. Cellular proteins and peptides are identified by high resolution mass spectrometry. SPECS was validated by identifying substrates of the Alzheimer protease BACE1 (Kuhn et al. EMBO J 2012). SPECS can be used for example to identify biomarkers and substrates of cell surface proteases.
Proteomic workflow for the label-free quantitative proteomic analysis of zebrafish brains (Hogl et al. Proteomics 2013): Brains are lysed in SDS to ensure efficient denaturation of proteins from all cellular compartments. Proteins are then tryptically digested on a filter using the FASP (filter-aided sample preparation) procedure (Wisniewski et al. Nat Meth 2009). Pure peptides are eluted from the filter and off-line fractionated using strong anion exchange to increase proteomic coverage. The peptide fractions are then subjected to high performance liquid chromatography coupled to tandem mass spectrometry. The obtained raw files from knockout and wild type samples are analyzed with MaxQuant and quantified using the LFQ and IBAQ algorithm. Proteins that accumulate in the brains of knockout fish are considered as putative BACE1 substrates.
Stefan Lichtenthaler studied chemistry at the Universities of Karlsruhe, Montpellier (France) and Heidelberg. He obtained his doctoral degree at ZMBH, Heidelberg University’s Center for Molecular Biology. After working as a postdoctoral researcher at Harvard University (USA) he led a junior research group at LMU Munich where he also acquired his teaching qualification (habilitation) for the field of biochemistry. In 2009 he was appointed head of department at DZNE, the newly established German Center for Neurodegenerative Diseases. Since 2012 he has been full professor of neuroproteomics at the Technische Universität Munich (TUM) and the DZNE.

Areas of investigation: Neurodegeneration – Proteases – Neuroproteomics
We study the function and regulation of proteins – in particular proteases – involved in neurodegenerative diseases, which affect more than one million patients in Germany. The goal of our research is to better understand the mechanisms of neurodegeneration and to develop novel biomarkers and drug targets for prevention or treatment of neurodegenerative diseases, in particular Alzheimer’s disease.
We study how membrane proteins are proteolytically cleaved at the cell surface. This process is called Regulated Intramembrane Proteolysis (RIP) and is a basic cellular mechanism controlling the communication between cells and their environment. RIP was first discovered in Alzheimer’s disease, but contributes to numerous (patho)physiological processes, from signal transduction to cell adhesion and from embryonic development to cancer. We study the molecular players - proteases, substrates and mechanisms - involved in RIP, in order to elucidate the biological function of this process and its connection to diseases. A current focus in the lab is on ADAM and BACE proteases in the nervous and immune system. Recently, we have developed a novel proteomic method called SPECS which allows us to identify substrates and functions of RIP proteases. In another recent study we used lentiviral RNA interference and identified the metalloprotease ADAM10 as the long-sought alpha-secretase in primary neurons. This protease has a central role in preventing the molecular mechanisms underlying Alzheimer’s disease.
We have an LTQ Orbitrap Velos and a Q Exactive mass spectrometer. We use quantitative mass spectrometry (label-free, dimethyl labeling, SILAC) to study proteins and their function in cells, tissues and whole organisms, such as zebrafish and mice. A focus is on proteins involved in neurodegeneration, for example the Alzheimer ADAM10 and BACE1 proteases or the TDP-43 protein linked to frontotemporal dementia. For example, we have developed the SPECS method for protease substrate identification from primary neurons. Another example is a novel workflow for quantitative proteomics of zebrafish which we have applied to fish lacking BACE1 or TDP-43. Besides mass spectrometry, we use modern biochemical and cell biological methods, such as siRNA screens, primary neuronal and glial cultures, lentiviral transduction and confocal microscopy.
