RefSeq Protein Record by Accession (TogoWS)

togows/protein-record

The NCBI RefSeq record of one protein (accession starting NP_, XP_, YP_ or WP_) through DBCLS TogoWS: accession and version, length, description, organism and taxonomy, the amino acid sequence, the annotated features (domains, binding sites, modified residues) and the literature references. Around 40 KB for a typical human protein. An unknown accession returns a record of null fields.

Data source

DBCLS TogoWS

Records from NCBI Gene and NCBI RefSeq, served through TogoWS (togows.dbcls.jp) of the Database Center for Life Science (DBCLS). Served by Eden Engine; not an official DBCLS or NCBI product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "togows/protein-record" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "togows/protein-record" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "togows/protein-record", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "togows/protein-record", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
