ProteomicsDeciphering Diazirine Reaction Mechanism: through Irradiation Modulation for Residue-Specific Distance Restraints in Protein Photo-Crosslinking
The diazirine photoreactive group has been widely used for photo-labeling and photo-cross-linking (PXL) of proteins. Yet, due to the mechanistic complexity of diazirine photo-reaction, site-specific and quantitative analysis of protein PXL data remains challenging. Herein, we have built an in-line p...

ProteomicsPPTC7 integrates homeostatic and physiological signals to regulate mitophagy and mitochondrial mass
Here we report that knockout of PPTC7, a mitochondrial matrix protein, hyperactivates BNIP3/NIX-mediated mitophagy in vitro and in vivo. Biochemically, the PPTC7 precursor is trapped by BNIP3 and NIX to mitochondrial outer-membrane, where PPTC7 scaffolds the assembly of the substrate-PPTC7- SCFFBXL4...
