Search across multiple organisms/databases
When multiple databases are selected here, then the specified search
criteria will be applied across all selected databases. Note that if many
databases are selected, queries can take a substantial amount of
time to complete. For this reason, a maximum of 70 databases can
be selected. Note that some search criteria may not be available for
Search by gene name or database identifier
Enter a gene name, or a database identifier from this database or from an external database to which this database contain links. Partial names will generate a substring search on gene names only (not on database identifiers).
Examples: "trpA", "trp", "b1236"
Search by protein or RNA name, EC number, or database identifier
Enter a protein or RNA name, an EC number, or a database identifier from this database or from an external database to which this database contain links. Partial names will generate a substring search on protein or RNA names only (not on database identifiers).
Examples: "tryptophan synthase", "P0A877", "18.104.22.168"
Search/Filter by sequence length
Search/Filter by replicon and/or gene map position
Search/Filter by product molecular weight
Search/Filter by product type/subunits
Search/Filter by product pI
Search/Filter by protein copy number
Search/Filter by small molecule regulator, cofactor, substrate or ligand
Enter a compound name and check one or more boxes. Use the autocomplete functionality to
select a full compound name, as no substring matching is done on the compound
Examples: "L-tryptophan", "pyruvate", "Mn+2"
Search/Filter by evidence code
Select one or more evidence codes to filter the result to only include gene products that have the corresponding evidence for their function. Deselecting all evidence codes has the same effect as selecting all evidence codes -- no filtering will be done based on evidence code.
Search/Filter by product cell component
Select one or more cell components to filter the result to only include gene products that have been assigned to those components. Note that not all proteins have been assigned to cell components. Deselecting all cell components has the same effect as selecting all cell components -- no filtering will be done based on cellular location.
Search/Filter by Gene Ontology term
Type in or browse for a Gene Ontology term
Filter to only include GO annotations with one of the checked evidence codes (optional):
Type in a GO term name or ID, browse GO to a particular gene product, or select one or more GO terms to filter your query to only retrieve gene products annotated with that term or terms. Only terms that have gene products annotated to them in this organism are available. If the Gene-Ontology-Terms class above has no children, then this organism lacks any GO annotations. To only include GO terms annotated with a particular evidence code, select one or more evidence codes. If no evidence codes are selected, then no filtering will be done based on evidence.
Search/Filter by MultiFun term
Browse MultiFun to a particular gene, or select one or more MultiFun terms to filter your query to only retrieve genes annotated with that term or terms. Only terms that have genes annotated to them in this organism are available. If the MultiFun class above has no children, then this organism lacks any MultiFun annotations.
Search/Filter by organism
Type in or browse for an organism
Type in an organism name or NCBI Taxonomy ID, or browse the NCBI Taxonomy to select one or more organisms or organism classes. The results will be filtered to only include genes and products belonging those organisms. Organisms that are not present in the list have no gene products curated for them. Deselecting all organisms has the same effect as selecting all organisms -- no filtering will be done based on organism.
Search/Filter by cited publication
Enter a PubMed ID, an author last name, and/or part of an article title in order to find genes and gene products that cite the corresponding publication or author.
Search/Filter by existence of protein features
If multiple feature types are specified, return proteins that have
of the specified types.
Select one or more protein feature types to filter the result to only include gene products for which features of those types have been identified. If no feature classes are listed, this database does not contain protein feature data.
