Manchester Proteome Profiler (MPP) is an open-source R Shiny application that streamlines the downstream analysis of quantitative proteomic data. Compatible with grouped protein intensities tables from MaxQuant, FragPipe, Proteome Discoverer, and other custom layouts, MPP provides an integrated platform for filtering, normalization, imputation, differential expression analysis, and cluster analysis across user-chosen experimental conditions. MPP supports both single- and dual-data set comparisons, incorporates SAINTexpress for affinity purification and proximity labeling experiments, and enables downstream analysis of the significant protein list clusters to functional enrichment and interaction networks via Gene Ontology, BioGRID, and STRING. Benchmarking with a KRAS proximity biotinylation data set demonstrated the ability of MPP to identify reproducible clusters of differentially expressed proteins and reveal biologically meaningful patterns, including enrichment of solute carrier transporters and adhesion molecules. With interactive visualizations, customizable reports, and support for complex experimental designs, MPP offers a novel, versatile, and user-friendly environment for proteomic data exploration and hypothesis generation.
