These are peptide regions used for antibody generation, indicating experimentally validated protein expression targets. Useful for immunology and antibody-based research. Get antigen sequences from Human Protein Atlas

Returns Ensembl gene, transcript, and translation IDs along with chromosome, start/end positions, and strand information. Essential for bridging protein annotations with genomic data. Get genome coordinate mappings for a protein

Shows canonical protein and related protein count for each gene. Use with a UniProt Proteome ID (e.g. UP000005640). Get the gene-centric view of a proteome

Each entry includes the wild-type and mutant residues, position, and a description of the functional impact. Critical for understanding structure-function relationships. Get mutagenesis experiments and phenotypic effects

Use a UniProt accession such as P12345, Q9Y6K9, or P53_HUMAN. Retrieve a full protein entry by UniProt accession

Features include domains, binding sites, active sites, signal peptides, transmembrane regions, disulfide bonds, glycosylation sites, and more. Each feature has start/end positions and evidence counts. Get sequence feature annotations for a protein

Returns taxonomy, protein count, gene count, reference status, and component information. Use IDs like UP000005640 for human proteome or UP000000589 for mouse. Get a specific proteome by UniProt Proteome ID

Shows which peptides have been experimentally detected and whether they are unique to this protein. Essential for validating protein expression. Get mass-spectrometry proteomics data for a protein

Provides residue-level PTM positions with evidence counts. Get post-translational modifications from mass-spec data

Returns scientific name, common name, rank, lineage, parent, and children nodes. Use IDs like 9606 for human, 10090 for mouse, 562 for E. coli. Get taxonomy node details by NCBI taxon ID

Each variant includes wild-type and mutant residues, clinical significance, consequence type (e.g. missense, nonsense), and cross-references. Critical for clinical genomics and variant interpretation. Get genetic variants for a protein from multiple sources

Valid types include: DOMAIN, BINDING, ACTIVE_SITE, SIGNAL, TRANSMEM, DISULFID, CARBOHYD, MOD_RES, VARIANT, MUTAGEN, REGION, MOTIF, SITE, REPEAT, COILED, COMPBIAS, HELIX, STRAND, TURN. Search features by type across proteins

You can combine gene name (e.g. TP53), organism (e.g. human, 9606), keyword (e.g. kinase), or accession. Returns a summarized list of matching proteins with names, organisms, and sequence lengths. Search proteins by gene name, organism, or keyword

Returns proteome IDs, taxonomy, protein counts, gene counts, and reference proteome status. Use queries like "homo sapiens", "escherichia coli", "arabidopsis". Search proteomes by organism name

Returns matching taxonomy entries with scientific names, common names, taxon IDs, and ranks. Useful for finding the correct taxon ID before querying proteins or proteomes for a specific organism. Search taxonomy by organism name

g. large_scale_study, uniprot, mixed), consequence type (e.g. missense, stop gained), and wild-type residue. Use this to find clinically relevant variants across the proteome. Search variants by consequence type, source, or residue
