This chapter presents an overview of the current status of studies on the structural and
molecular biology of the retinoid X receptor subtypes α, β, and γ (RXRs, NR2B1–3), their …

The molting process in arthropods is regulated by steroid hormones acting via nuclear
receptor proteins. The most common molting hormone is the ecdysteroid, 20 …

Conservation of a molecular target across species can be used as a line-of-evidence to
predict the likelihood of chemical susceptibility. The web-based Sequence Alignment to …

Zooecdysteroids (arthropod steroid hormones) regulate the development of arthropods and
probably many other invertebrates. Phytoecdysteroids are analogues occurring in a wide …

In 1974, Ashburner and colleagues postulated a model to explain the control of the puffing
sequence on Drosophila polytene chromosomes initiated by the molting hormone 20 …

Ecdysone receptor (EcR) plays important roles in molting, metamorphosis, and reproduction
of insects. EcR ortholog and its function in melon aphid Aphis gossypii have not been …

The nuclear receptors (NRs) of metazoans are an ancient family of transcription factors
defined by conserved DNA-and ligand-binding domains (DBDs and LBDs, respectively) …

Several reviews devoted to various aspects of ecdysone research have been published
during the last few years. Therefore, this article concentrates mainly on the considerable …

Whitefly (Bemisia tabaci Gennadius) is a hemipteran phyto polyphagous sucking insect pest
which is an important pest of cotton that causes economic losses to the crop by reducing its …

Publisher Summary This chapter examines the information gathered about the ecdysteroid
receptor at three levels and provides brief descriptions and references for the tools used to …
