[2023-11] Sara’s paper IDPpub: Illuminating the Dark Phosphoproteome Through PubMed Mining has been published in Molecular & Cellular Proteomics. Phosphorylation is an essential component of cellular signaling, and phosphoproteomics enables global identification and quantification of phosphosites from biological samples. However, interpretation of phosphoproteomic findings is hindered by our limited knowledge on functions, phenotype associations, and regulating enzymes of the phosphosites. We developed a computational pipeline that uses BioBERT to extract phosphorylation sites from biomedical abstracts. The pipeline further aligns the sites to human and mouse reference sequences to facilitate computational applications and intersection with mass spectrometry experiments. The extracted evidence sentences can be used to identify regulating enzymes and biological functions. We made all data available in the IDPpub web portal for easy exploration.
[2023-10] The review article Current perspectives on mass spectrometry-based immunopeptidomics: the computational angle to tumor antigen discovery co-authored by Drs. Zhang and Bassani-Sternberg has been published in The Journal for ImmunoTherapy of Cancer.

[2023-09] Yongchao’s paper SEPepQuant enhances the detection of possible isoform regulations in shotgun proteomics has been published in Nature Communications. Shotgun proteomics is crucial for identifying and quantifying proteins in biomedical research. However, characterizing protein isoforms is challenging due to shared peptides among proteins. We introduce SEPepQuant, a graph theory-based method to tackle this challenge. SEPepQuant addresses limitations of existing methods, enhancing isoform characterization, identifying isoform-level regulation events, and facilitating cross-study comparisons. Our results support a significant role of protein isoform regulation in normal and disease processes, making SEPepQuant valuable for biological and translational research. Source code is available in the Zhang Lab GitHub.

[2023-08] Our paper A proteogenomics data-driven knowledge base of human cancer has been published in Cell Systems. Congratulations to Yuxing, Sara, and all co-authors! This paper describes LinkedOmicsKB, a knowledge base built upon consistently processed and systematically precomputed CPTAC pan-cancer proteogenomics data. With approximately 40,000 gene-, protein-, mutation-, and phenotype-centric web pages, it enables anyone with internet access to conduct meaningful inquiries into CPTAC data, facilitating data-driven scientific discoveries. The paper uses three case studies to illustrate the practical utility of LinkedOmicsKB in providing new insights into genes, phosphorylation sites, somatic mutations, and cancer phenotypes.

All processed data tables can be accessed at the Proteome Data Commons.
[2023-08] The CPTAC study Proteogenomic insights suggest druggable pathways in endometrial carcinoma has been published in Cancer Cell. Congratulations to Yongchao and all co-authors! Some of the key findings include identifying two peptides that can predict antigen processing and presentation machinery activity, revealing a potential role for metformin treatment in non-diabetic patients with elevated MYC activity, discoverying PIK3R1 in-frame indels as a primary driver of elevated AKT phosphorylation and increased sensitivity to AKT inhibitors, and connecting CTNNB1 hotspot mutations to pS45 phosphorylation-induced degradation of β-catenin.

[2023-04] Bo’s paper PepQuery2 democratizes public MS proteomics data for rapid peptide searching has been published in Nature Communications. One of the most important milestones in proteomics is the Amsterdam Principles, which require mandatory raw MS/MS data deposition to promote broad reuse of the data. However, because of the challenges involved in understanding, downloading, analyzing, and interpreting MS/MS data, investigation and reuse of these public data are largely restricted to computational proteomics researchers. By enabling rapid identification of any known or novel peptide sequences of interest in any local or publicly available MS-based proteomics datasets in a targeted manner, PepQuery2 provides a practical solution that makes public MS/MS data easily useful to the general research community. Both the command line version and the web version of PepQuery2 are available at http://www.pepquery.org. The source code of PepQuery2 is available at https://github.com/bzhanglab/PepQuery.
