Human Protein Atlas
The Human Protein Atlas is a life science data website for exploring human protein expression across tissues, cells, organelles, cancers, blood, and downloadable datasets.
What the Human Protein Atlas is
The Human Protein Atlas is a life science data website at proteinatlas.org for exploring human proteins across tissues, cells, organelles, cancer contexts, blood, and other biological views. It combines antibody-based imaging, transcriptomics, proteomics, and systems biology resources to help users inspect where proteins are expressed and localized.
Protein pages
Protein pages connect gene and protein identifiers with expression evidence, images, tissue patterns, cell-type information, subcellular localization, cancer-related data, and external references. These pages are useful for orientation, but they are not a substitute for reading methods, evidence levels, and source context.
Tissue expression
The tissue resource helps users explore protein and RNA expression across human tissues and organs. It is especially useful when asking whether a gene or protein appears broadly expressed, enriched in a tissue, or tied to a biological system that deserves closer study.
Cell and subcellular views
The single-cell and subcellular resources add finer biological resolution. Single-cell views can help identify cell-type expression patterns, while subcellular data can show where proteins are detected inside cells, such as nuclei, membranes, cytosol, organelles, or other compartments.
Pathology resource
The pathology resource connects expression patterns with cancer-related contexts and survival-style views where available. These data can support biomarker exploration and hypothesis generation, but clinical interpretation requires validation, study design context, and medical expertise.
Downloads and data access
Human Protein Atlas provides downloadable data and data access guidance for people who need computational reuse. Bulk files and structured exports can support reproducible analysis, database integration, machine learning, teaching, and cross-resource comparison with Ensembl, UniProt, Reactome, and Gene Ontology.
Strengths and limits
The atlas is powerful because it gathers many protein evidence types into one website, but each evidence type has limits. Antibody staining, RNA abundance, mass spectrometry, image analysis, cell-type modeling, sample selection, and release version all affect what a signal can safely support.
Why it matters
The Human Protein Atlas matters because proteins are the working molecules behind much of cell biology, disease research, diagnostics, and drug discovery. A public atlas helps researchers and students move from gene names to spatial, cellular, and tissue-level evidence about human biology.
