The gene product name assignment procedure used in the DOE-JGI MAP. Genes are first compared to protein families (COGs, Pfam, TIGRfam) and protein databases (KEGG, IMG). A product name is assigned through a series of checks to identify significant hits to IMG terms and the protein families databases. At the end of the process translation tables are used to produce a Genbank compliant product name from the respective source.
