Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.

Primary database (GenBank) nucleotide records reported in the current articles as well as Reference Sequences (RefSeqs) that include the articles as references.

Nucleotide records associated with the current articles through the Gene database. These are the related sequences on the Gene record that are added manually by NCBI.

Protein records associated with the current articles through related Gene database records. These are the related sequences on the Gene record that are added manually by NCBI.

PubChem chemical substance (submitted) records that are classified under the same Medical Subject Headings (MeSH) controlled vocabulary as the current articles.

Taxonomy records associated with the current articles through taxonomic information on related molecular database records (Nucleotide, Protein, Gene, SNP, Structure).

UniGene clusters of expressed sequences that are associated with the current articles through references on the clustered sequence records and related Gene records.

Protein translation features of primary database (GenBank) nucleotide records reported in the current articles as well as Reference Sequences (RefSeqs) that include the articles as references.
