Using CoSpred users can create their own machine learning compatible training dataset and then train a machine learning model to predict both backbone and non-backbone ions. For the model a transformer encoder architecture is used to predict the complete MS/MS spectrum from a given peptide sequence. In addition to the transformer model provided in the package, the code is built modularly to allow for alternate ML models to be easily \"plugged in,\" allowing for spectrum prediction optimization given different experimental conditions.

Although initially discovered as an essential regulator of cell division, Pin1 has since been identified as a regulator of many biological processes and is associated with numerous malignancies and neurodegenerative disorders. Pin1 has been shown to influence phosphorylation by modulating phosphatase accessibility. However, it can also indirectly regulate phosphorylation by isomerizing peptidyl-prolyl bonds on kinases, affecting their subcellular localization and/or substrate specificity. Here, SILAC-based mass spectrometry was employed to identify proteomic and phosphoproteomic changes in human osteosarcoma human osteosarcoma cell line (U2-OS) cells in response to treatment with the selective covalent Pin1 inhibitor Sulfopin. We confirmed that Sulfopin covalently binds Pin1 and profiled Pin1-dependent changes to the proteome and phosphoproteome, identifying 803 phosphosites that underwent significant Sulfopin-dependent changes. The identified phosphosites include substrates for a number of distinct kinases, including protein kinase B (AKT1), aurora kinase A (AURKA), cyclin-dependent kinase (CDK)1 and CK2. Overall, this study reveals the broad impact of Sulfopin on the phosphoproteome, improving our understanding of how Pin1 modulates complex regulatory kinase networks in living cells.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Summary</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>\u0000 <p>The peptidyl-prolyl isomerase (PPIase) Pin1 has emerged as a potential therapeutic target for numerous malignancies and neurodegenerative disorders based on its altered expression in several diseases.</p>\u0000 </li>\u0000 \u0000 <li>\u0000 <p>As the activity of Pin1 is phosphorylation-dependent, it is intimately involved with constituents of regulatory kinase networks within cells.</p>\u0000 </li>\u0000 \u0000 <li>\u0000 <p>To elucidate how Pin1 orchestrates regulatory signalling within cells, we performed quantitative proteomic and phosphoproteomic profiling of SILAC-labelled human osteosarcoma U2-OS cells treated with Sulfopin, a highly selective covalent Pin1 inhibitor.</p>\u0000 </li>\u0000 \u0000 <li>\u0000 <p>In addition to demonstrating that Pin1 inhibition alters the abundance and phosphorylation of proteins involved in a variety of fundamental cellular processes, these studies revealed that Pin1 inhibition modulates the ","PeriodicalId":224,"journal":{"name":"Proteomics","volume":"25 14","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pmic.13980","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biostimulants, such as humic substances, are currently being applied as a strategy to increase plant nutrient-use efficiency and minimize environmental impacts within cropping systems. One of these biostimulants is Humalite, which is a unique, naturally occurring coal-like substance found in deposits across southern Alberta. These deposits contain exceptionally high ratios of humic acids (>70%) and micronutrients due to their unique freshwater depositional environment. Humalite has begun to be applied to fields based on scientific data suggesting positive impacts on crop growth, yield, and nutrient usage; however, little is known about the underlying molecular mechanisms of Humalite. Here, as part of a larger field study, we report a quantitative proteomics approach to identify systems-level molecular changes induced by the addition of different Humalite application rates in field-grown wheat (<i>Triticum aestivum</i> L.) under three urea fertilizer application rates. In particular, we see wide-ranging abundance changes in proteins associated with several metabolic pathways and growth-related biological processes that suggest how Humalite modulates the plant molecular landscape.
