ULTRASPIRACLE LIGAND BINDING DOMAIN FROM DROSOPHILA MELANOGASTER
Overview
Ultraspiracle (USP) is the invertebrate homologue of the mammalian, retinoid X receptor (RXR). RXR plays a uniquely important role in, differentiation, development, and homeostasis through its ability to serve, as a heterodimeric partner to many other nuclear receptors. RXR is able to, influence the activity of its partner receptors through the action of the, ligand 9-cis retinoic acid. In contrast to RXR, USP has no known, high-affinity ligand and is thought to be a silent component in the, heterodimeric complex with partner receptors such as the ecdysone, receptor. Here we report the 2.4-A crystal structure of the USP, ligand-binding domain. The structure shows that a conserved sequence motif, found in dipteran and lepidopteran USPs, but not in mammalian RXRs, serves, to lock USP in an ... [(full description)]
