NF-KappaB Orthologue in Fruitfly (Drosophila melanogaster)

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


NF-KappaB (Nuclear factor-KappaB)/Rel proteins are dimeric, sequence-specific transcription factors involved in the activation of an exceptionally large number of genes in response to inflammation, viral and bacterial infections, and other stressful situations requiring rapid reprogramming of gene expression. Rel/NF-KappaB transcription factors include a collection of proteins, conserved from the fruit fly Drosophila melanogaster to humans. Among the commonly used model organisms, these transcription factors are notably absent in yeast and the nematode Caenorhabditis elegans; in part, this may be because one of the primary roles of these factors is to control a variety of physiological aspects of immune and inflammatory responses. A pathway similar to the Rel/NF-KappaB signaling pathway may also control certain defense responses in plants (Ref.1).
