Aliases — alternative gene or protein names stored in the database. Type at least 3 characters to see autocomplete suggestions from existing entries. Partial matches are supported (e.g. synapto will match synaptobrevin).

Foreign annotation — free-text search across the external annotation field. Enter any keyword, gene description, or NCBI identifier (e.g. gi|21426793 or putative synaptobrevin). Partial matches are supported.

Shortname — a compact species code derived from the genus and species name (first two letters each).

Type at least 2 characters to search organisms by shortname. Results appear in the panel below grouped by taxonomic rank — tick the checkboxes to include those organisms in the query. Use Select all / Clear to manage the whole list at once. The shortname can also include an isoform or protein suffix after an underscore (e.g. HoSa_Syx1).

Scientific name — full or partial organism name (e.g. Homo, Arabidopsis thaliana). Type at least 3 characters to search. Case-insensitive; results appear in the same panel as the shortname search, grouped by taxonomic rank (genus, species, subspecies, …).

Taxonomy filters (Taxonomy, shortname and scientific name) are mutually exclusive. Filling one will reset the others.
