The Human Protein Atlas

The search function can be used for free text search (type anything in the search field), or for more complex queries using "Fields" (see examples).

The free text search will scan for complete and partial matches to gene names, gene synonyms, gene descriptions, external (UniProt, Ensembl, NCBI Entrez Gene) gene and protein identifiers, protein classes, Gene Ontology identifiers and descriptions, antibody identifiers and image annotations. The free text query word needs to be at least three characters long.

Specific fields can be searched by using the "Fields"-function. Available fields are: Gene name (HGNC name or synonyms), Protein class, Chromosome, External identifier (Ensembl gene, transcript or protein identifier, UniProt accession number, NCBI Entrez gene identifier), Subcellular location based on immunofluorescent staining in three different cell lines, Organ-, Tissue-, Cancer- and Cell line expression, Antibody validation results in four different assays (IH=immunohistochemistry, IF=immunoflourescence, WB=Western blot, PA=Protein array), evidence scores and a filtration on Genes with antibodies only and Genes with knowledge-based annotated protein expression (IH, IF).
