From: BioGPS: an extensible and customizable portal for querying and organizing gene annotation resources

A partial list of BioGPS plugins. Valid URLs can be formed by substituting gene-specific variables in the URL templates above. For example, for the gene CDK2, {{Symbol}} = CDK2, {{EntrezGene}} = 1017 (or 12566 for mouse), {{EnsemblGene}} = ENSG00000123374, {{HGNC}} = 1771, {{HPRD}} = 00310, {{MGI}} = 104772, and {{RGD}} = 70486. Plugin URL templates can also utilize variables for Unigene ID, RefSeq transcript or protein IDs, Protein Data Bank (PDB) ID, and Online Mendelian Inheritance in Man (OMIM) accession.
