Immune system is a complex machinery, which is based on the highly coordinated expression of a wide array of genes and proteins. IKB now covers three databases which were independent earlier: Immunome Database, ImmTree and ImmunomeBase, and additional data.

IKB contains information about immunity related proteins, their domain structure and the related ontology terms. Information can be found also about the localization of the coding genes and their comparison with the existing mouse orthologs. Phylogenetic trees re available for orthologs from species.
Orthologs for genes in metazoan organisms are available and clustered into two classes or levels.

Vertebrate immunoglobulins (IG), T cell receptors (TR) and major histocompatibility complex (MHC) were excluded from Immunome KnowledgeBase as they are specific of the adaptive immune response and because they are well covered in IMGT®, the international ImMunoGeneTics information system®.
