Ecdysteroids
Ecdysteroids are insect moulting and sex hormones which include ecdysone and its homologues such as 20-hydroxyecdysone. Ecdysteroids also occur in other invertebrates where they can play a different role. They also appear in many plants mostly as a protection agents (toxins or antifeedants) against herbivore insects. These phytoecdysteroids have medicinal value and are part of herbal adaptogenic remedies like cordyceps.
Physiological functions of EcR
Pulses of 20-hydroxyecdysone occur during insect development, whereupon this hormone binds to the ecdysone receptor, a ligand-activated transcription factor found in the nuclei of insect cells. This in turn leads to the activation of many other genes, as evidenced by chromosomal puffing at over a hundred sites. Ultimately the activation cascade causes physiological changes that result in ecdysis (moulting).
Potential applications of GAL4-EcR LBD
By the addition of lipid ligands(ecdysteroids), the created system activates the expression of any kind of genes fused to UAS(upstream activation seqence)previously. Also can be used as a lipid sensor by activating reporter genes (e.g. Luciferase).
