RefSeq identifiers

To create our terminology containing both internal terms and external terms we semiautomatically extract terms from available external resources (e.g., MeSH, EMTREE, UniProt). Then we fit the extracted terms to our data structure and preserve the reference to the source system because sometimes terms are very specific to certain databases. We refer to the terms specific to a database as local terms. These local terms are stored in a dedicated data structure, the Metastore. It must be noted that we refer to accession codes and identifiers used in databases such as UniProt, RefSeq, and GO as local terms (see Tables 31.1 and 31.2). 

Figure 8.14. Spliced alignment. The sim4 program was used to align a novel human mRNA (RefSeq NM 015372) to the genomic sequence of a cosmid from chromosome 22 (EMBL Z82248). Three exons were identified on the complementary strand (the third one has been truncated for brevity). The " >" symbols indicate splice sites found at the exon/intron boundaries.

The UniProt Archive (UniParc) provides a stable, comprehensive, nonredundant sequence collection by storing the complete body of publicly available protein sequence data. Although most protein sequence data are derived from the translation of DDBJ/EMBL/GenBank sequences, primary protein sequence data are also submitted directly to UniProt or derived from the PDB entries. The Archive also captures protein sequence data from other sources such as Ensemble, International Protein Index (IPI), NCBI-RefSeq, FlyBase, and WormBase. Each protein sequence is assigned to a unique UniParc identifier (UPI ) and represented only once in the Archive. In UniParc, the...
