POGs is a relational database that integrates data from rice, maize, and Arabidopsis by placing the complete Arabidopsis and rice proteomes, and the available maize sequences into "putative orthologous groups" (POGs). POGs were assigned using InParanoid.
Each POG entry includes cross-referenced orthologs and paralogs in Arabidopsis and rice, annotated with domain organization, gene models, phylogenetic trees showing closely-related proteins, and intracellular targeting predictions. The database can be queried to identify POGs with specific domain combinations and predicted intracellular locations.
Search(multiple terms in the same or different field will be linked with "AND".)
Annotation Tool Now AvailableA tool for community annotation is now available. We welcome your input about POG assignments, literature citations, experimentally-verified protein function and localization, etc. To suggest annotations, click on "Annotate" on the relevant POG page.
