ProteomicsCross-linking of the Endolysosomal System Reveals Potential Flotillin Structures and Cargo
Lysosomes are well-established as the main cellular organelles for the degradation of macromolecules and emerging as regulatory centers of metabolism. They are of crucial importance for cellular homeostasis, which is exemplified by a plethora of disorders related to alterations in lysosomal function...

ProteomicsFinding New Drug Targets for Niemann Pick Type C Hepatic Disease Based On Proteomic Network Analysis
A significant area of rare diseases research is the investigation of druggable protein encoding genes that contribute to pathogenesis. Niemann Pick Type C (NPC) disease can be considered as a challenging one, among all rare diseases, because it has been associated with a poor prognosis and an unclea...

ProteomicsGOLPH3 and GOLPH3L maintain Golgi localization of LYSET and a functional mannose 6-phosphate transport pathway
Glycosylation plays an important role for modifications of lipids and sorting of proteins that is regulated by asymmetric intra-Golgi distribution and SPPL3-mediated cleavage of Golgi enzymes. We found that cells lacking the Golgi N-acetylglucosamine phosphotransferase (GNPT) retention factor LYSET/...

ProteomicsThe mitochondrial Hsp70 controls the assembly of the F1FO-ATP synthase
The mitochondrial F1FO-ATP synthase produces the bulk of cellular ATP. The soluble F1 domain contains the catalytic head that is linked via the central stalk and the peripheral stalk to the membrane embedded rotor of the Fo domain. The assembly of the F1 domain and its linkage to the peripheral stal...

ProteomicsInvestigation of Oligodendrocyte Precursor Cell Differentiation by Quantitative Proteomics
Oligodendrocytes, the myelinating cells of the central nervous system, are essential for correct brain function. They originate from oligodendrocyte precursor cells (OPCs) through a differentiation process which is only incompletely understood and impaired in a variety of demyelinating diseases. Bet...

ProteomicsThe Human Disease Gene LYSET is Essential for Lysosomal Enzyme Transport and Viral Infection
Lysosomes are key degradative compartments of the cell. Transport to lysosomes ismediated by tagging soluble enzymes with mannose 6-phosphate (M6P) by GlcNAc-1-phosphotransferase whose deficiency leads to the severe lysosomal storage disorder mucolipidosisII (MLII). Several viruses require lysosomal...

ProteomicsRapiGest Precipitation Depends on Peptide Concentration
The mass spectrometry-compatible surfactant RapiGest promotes the enzymatic digestion of proteins by facilitating their unfolding while retaining enzymatic activity. RapiGest consists of a hydrophilic head and a hydrophobic tail, which can be separated by acid hydrolysis. This allows for removal of ...

ProteomicsTwo step enrichment facilitates background reduction for proteomic analysis of lysosomes
Lysosomes comprise the main degradative compartment of almost all mammalian cells and are involved in various cellular functions, most of which are catalyzed by the lysosomal proteome. Lysosomal proteins are low abundant, complicating their analysis by mass spectrometry-based proteomics. To increase...

ProteomicsTargeted Quantification of the Lysosomal Proteome in Complex Samples
The lysosome, as the main degradative organelle of eukaryotic cells, is involved in numerous cellular processes. A defect in one of its proteins often results in lysosomal storage diseases (LSDs). For the study of lysosomal proteins, mass spectrometry (MS) has emerged as the method of choice. Lysoso...
