ProteomicsAn Uncommon Phosphorylation Mode Regulates the Activity and Protein Interactions of N-Acetylglucosamine Kinase
Reversible protein phosphorylation serves as a pivotal signaling mechanism in eukaryotic cells, contrasting with the poorly understood protein pyrophosphorylation, a posttranslational modification (PTM) whose functions in living organisms remain elusive. Unlike kinase-mediated protein phosphorylatio...

ProteomicsInteraction with IP6K1 supports pyrophosphorylation of substrate proteins by the inositol pyrophosphate 5-IP7
HEK293T cells transiently transfected to express either SFB-tagged GFP or SFB-tagged IP6K1 were lysed in NETN buffer (20 mM Tris-HCl, pH 8.0, 100 mM NaCl, 1 mM EDTA, 0.5% Nonidet P-40) containing protease and phosphatase inhibitor cocktails (Merck), at 4 degree C for 60 min. Cell debris were removed...

ProteomicsPyrophosphoproteomics: extensive protein pyrophosphorylation revealed in human cell lines
Reversible protein phosphorylation is a central signaling mechanism in eukaryotic cells. While the identification of canonical phosphorylation sites using mass-spectrometry (MS) based proteomics has become routine, annotation of non-canonical phosphorylation has remained a challenge. Here, we report...
