Our lipid detecting tool kit comprosis of 19 basic parts (11 ligand binding domains, 3 DNA binding domains and 5 other basic parts),9 composite chimeric receptors and 3 plasmid expression vectors and associated intermediates. Amongst our kit, parts of various speicies of the animalia kingdom may be found. The composite receptors are proof of concept that the basic parts acctually work. The bulk of the data (sequance, sub domains, 3d structure, ligand affinity and more..) can be found in the parts registry.
Ligand binding domains - Basic Parts
The ecdysone receptor is a nuclear receptor found in arthropods, where it controls development and contributes to other processes such as reproduction. The receptor is a non-covalent heterodimer of two proteins, the EcR protein and ultraspiracle protein (USP). It binds to and is activated by ecdysteroids. 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, which ultimately causes physiological changes that result in ecdysis (moulting). Go to the official parts registry page for this part
The nuclear hormone receptor DAF-12 from Caenorhabditis elegans is activated by dafachronic acids, which derive from sterols upon oxidation by DAF-9, a cytochrome P450. DAF-12 activation is a critical checkpoint in C. elegans for acquisition of reproductive competence and for entry into adulthood rather than dauer diapause.

Nuclear hormone receptor family member nhr-8 The nhr-8 gene encodes a nuclear hormone receptor homolog; nhr-8(ok186) mutants have abnormally low resistance to the toxins colchicine and chloroquine. NHR-8 functions in the nematode xenobiotic defense system.

Nuclear hormone receptor family member nhr-23. The nhr-23 gene encodes a nuclear hormone receptor homolog that is required in all larval molts; NHR-23 is highly similar to Drosophila DHR3, an ecdysone-inducible gene product involved in metamorphosis. The NHR-23 protein is nuclear, and is present in all blastomeres during early embryogenesis; during later stages of morphogenesis, NHR-23 is restricted to epidermal cells. nhr-23 expression cycles between stages of larval development; during each intermolt period, levels of nhr-23 transcripts are 2-5 times greater than levels at each molt. NHR-23 binds the DRS-type hormone response sequence in vitro

Nuclear hormone receptor family member nhr-25. nhr-25 encodes a nuclear hormone receptor orthologous to Drosophila Ftz-F1; NHR-25 is required for embryogenesis, molting, vulval and gonadal development, and hypodermal expression of acn-1; nhr-25 is expressed in gonads and loaded into embryos as a maternal transcript; nhr-25 is zygotically expressed in progeny of the E cell, and then in hypodermis and gut; the role of NHR-25 in molting may be evolutionarily conserved between nematodes and arthopods.

Nuclear hormone receptor family member nhr-31 nhr-31 encodes one of over 200 C. elegans nuclear receptors; nhr-31 activity is required for proper growth, development, and function of the excretory cell; in regulating excretory cell development, NHR-31 appears to function by controlling the expression of genes encoding subunits of the vacuolar ATPase; an nhr-31::gfp promoter fusion is expressed at high levels in the excretory cell beginning at embryogenesis and continuing through adulthood, with lower levels of expression seen in the intestine and unidentified tail cells.

NHR-80 encodes a nuclear hormone receptor, expressed in the intestine, that regulates expression of the delta-9 desaturases FAT-5/-6/-7, and thus regulates fatty acid metabolism. nhr-80 is specific to nematodes, being a divergent ortholog of HNF4 with many paralogs in C. elegans
