From: Definition, conservation and epigenetics of housekeeping and tissue-enriched genes
Biological processes enriched in housekeeping genes. Enriched biological processes (E value < 0.05) and their ancestors from the Panther Ontology are shown in a hierarchical structure. E values were calculated by hypergeometric distribution with a Bonferroni correction. The intensity of color is proportional to the significance of gene enrichment (-log(E value), ranging from the lightest 2.3 to the darkest 39.1).
