ProteomicsA quantitative proteomics screen identifies a substrate repertoire of rhomboid protease RHBDL2 in human cells and implicates it in epithelial homeostasis.
Rhomboids are intramembrane serine proteases conserved in all kingdoms of life. They regulate epidermal growth factor receptor signalling in Drosophila by releasing signalling ligands from their transmembrane tethers. Their functions in mammals are poorly understood, in part because of the lack of e...

ProteomicsStructural basis for the mechanisms of human presequence protease conformational switch and substrate recognition
Presequence protease (PreP) degrades presequence peptides cleaved off from nuclear-encoded proteins and other aggregation-prone peptides, such as amyloid β (Aβ). PreP structures have only been determined in a closed conformation; thus, the mechanisms of substrate binding and selectivity remain elusi...

ProteomicsSubstrate profiling of mitochondrial caseinolytic protease P via a site-specific photocrosslinking approach
The function of proteases is mainly determined by the substrates they are processing. However, substrate identification remains a challenging task. Here, we used genetic code expansion to incorporate a diazirine-lysine amino acid (DiazK) at selected positions of mitochondrial caseinolytic protease P...

ProteomicsTime-resolved inducible knock-down of Clp protease subunits in tobacco identifies putative protease substrates
The Clp protease complex in plants is the one with the highest complexity through all life kingdoms. It is composed of 14 nuclear- and plastid-encoded subunits which are allocated in different rings across the complex. The proteolytic ring (P-ring; ClpP3-ClpP6) and non-proteolytic ring (R-ring; ClpR...

ProteomicsA chemical strategy for protease substrate profiling
Here, we introduce a simple method, termed CHOPS, for the discovery of protease substrates. CHOPS exploits a 2-pyridinecarboxaldehyde (2PCA)-biotin probe, which selectively biotinylates protein N-termini except those with proline in the second position. CHOPS can, in theory, discover substrates for...

ProteomicsMPP profiling in yeast - Quantitative profiling for substrates of the mitochondrial presequence processing protease reveals a set of non-substrate proteins increased upon proteotoxic stress
The majority of mitochondrial preproteins is targeted via N-terminal presequences that are cleaved upon import into the organelle. The essential mitochondrial processing protease (MPP) is assumed to cleave the majority of incoming precursors. However, only few substrate proteins of MPP have been exp...
