ProteoViz: a tool for the analysis and interactive visualization of phosphoproteomics data

Area of Science:

• Proteomics
• Bioinformatics
• Systems Biology

Background:

• Quantitative proteomics, particularly phosphoproteomics, generates large, complex datasets.
• Advanced tools are needed for efficient analysis and visualization of protein and phosphopeptide data.

Purpose of the Study:

• To develop ProteoViz, a set of R scripts for streamlined analysis and visualization of phosphoproteomics data.
• To enable identification of differentially expressed proteins, phosphopeptides, sequence motifs, kinases, and enriched pathways.

Main Methods:

• Development of an R-based software package, ProteoViz.
• Implementation of normalization and differential expression analysis for proteins and phosphopeptides.
• Integration of interactive visualization tools for user-friendly exploration of results.

Main Results:

• ProteoViz successfully analyzes and visualizes phosphoproteomics data.
• The tool links significant phosphosites to sequence motifs and biological pathways.
• Demonstrated functionality using a phosphoproteomic dataset from lymphoma cell lines treated with kinase inhibitors.

Conclusions:

• ProteoViz provides a valuable resource for the phosphoproteomics community.
• The tool facilitates the interpretation of experimental conditions and guides future research.
• Freely available scripts and data enhance reproducibility and accessibility.
