A CONSERVED SIGNALING PATHWAY: The Drosophila Toll-Dorsal Pathway

Belvin, Marcia P., Anderson, Kathryn V.·1996·Annual Review of Cell and Developmental Biology

Abstract

▪ Abstract The Toll-Dorsal pathway in Drosophila and the interleukin-1 receptor (IL-1R)-NF-κB pathway in mammals are homologous signal transduction pathways that mediate several different biological responses. In Drosophila, genetic analysis of dorsal-ventral patterning of the embryo has defined the series of genes that mediate the Toll-Dorsal pathway. Binding of extracellular ligand activates the transmembrane receptor Toll, which requires the novel protein Tube to activate the cytoplasmic serine/threonine kinase Pelle. Pelle activity controls the degradation of the Cactus protein, which is present in a cytoplasmic complex with the Dorsal protein. Once Cactus is degraded in response to signal, Dorsal is free to move into the nucleus where it regulates transcription of specific target genes. The Toll, tube, pelle, cactus, and dorsal genes also appear to be involved in Drosophila immune response. Because the IL-1R-NF-κB pathway plays a role in vertebrate innate immunity and because plant homologues of the Toll-Dorsal pathway are important in plant disease resistance, it is likely that this pathway arose before the divergence of plants and animals as a defense against pathogens.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
