The target of rapamycin (TOR)1 kinase functions as a key integrator for diverse growth-stimulating and inhibitory signals originating from amino acids, energy levels, stress, oxygen, and growth things (1). TOR is definitely an atypical serinethreonine kinase conserved in all eukaryotes and is usually a vital regulator of energy-demanding processes such as protein synthesis, the cell cycle, metabolism, and autophagy (two). Dysregulation of TOR signaling has been implicated in many diseases, including cancer, neurodegenerative disorders, obesity, and diabetes. Consequently, the capacity to modulate TOR signaling is of great pharmacological interest (three). Rapamycin, a potent inhibitor of TOR complex 1 (TORC1), is really a clinically approved immunosuppressant drug which is utilized to prevent organ transplant rejection. Intriguingly, studies in yeast (four), flies (5), and worms (6) suggest that inhibition of TOR signaling extends lifespan, probably by mimicking dietary restriction. Moreover, current research demonstrated, for the first time, that it is actually feasible to raise the lifespan of mice pharmacologically by treating the mice with rapamycin (7, 8), though, it remains unclear whether or not rapamycin increases lifespan by delaying age-associated diseases or by slowing aging. It is nicely established that posttranslational modifications (PTMs) serve as the basis for signal transduction inside the cell. Advancements in mass spectrometry (MS)-based proteomics have significantly facilitated the large-scale identification and1 The abbreviations applied are: TOR, target of rapamycin; TORC1, target of rapamycin complicated 1; SILAC, steady isotope labeling with amino acids in cell culture; PTM, posttranslational modification; diGly, di-glycine; MS, mass spectrometry; GO, Gene Ontology; SCX, sturdy cation exchange chromatography; NEDD, neural precursor cell expressed developmentally down-regulated protein; Art, arrestin-related trafficking adaptor.Molecular Cellular Proteomics 13.phosphorylation and Ubiquitylation Dynamics in TOR Signalingquantification of several PTMs on a international scale (9, ten). Saccharomyces cerevisiae (normally generally known as baker’s yeast) has been widely used as a eukaryotic model organism for in-depth evaluation of proteome (11), phosphoproteome (12), and acetylome (13). Lots of from the identified PTM internet sites have been shown to become conserved from yeast to mammals (14). Conjugation of.
