InnateDB Innate Immunity Genes

Aside from annotating innate immunity interactions and pathways, the InnateDB curation team has also established a project to annotate genes that have a role in the innate immune response. This has been initiated in response to the fact that Gene Ontology annotation of the innate immune response is quite limited in the numbers of genes which have been identified and in response to the fact that many users have been eager to have a defined list of innate immune genes. For innate immune gene annotation, curators employ a new tool in the InnateDB curation system to associate relevant genes with publications which provide evidence for that gene having a role in innate immunity. Along with the link to the relevant publication(s), the curators provide a one-line summary of the role similar to Entrez GeneRIFs. Such genes are also automatically associated with the Gene Ontology term "innate immune response" in InnateDB, which provides a more comprehensive list of these genes for use in the InnateDB Gene Ontology over-representation analysis tool. To date, 1693 genes have been annotated to some extent (as this is an on-going process). It should be noted that it is not the intention of InnateDB to comprehensively annotate all the roles of a given gene, but rather to provide a brief indication if a gene has a role in innate immunity. You can download all InnateDB curated genes with their annotations as Excel sheet.

This list provides details of the 2308 genes which have been annotated by either InnateDB or Gene Ontology as having a role in the innate immune response and is updated weekly.
