Ligand binding domains - Basic Parts

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364310 Ecdysone Receptor Ligand Binding Domain (D. Melanogaster)]

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).

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364303 DAF 12 Nuclear Receptor(C. Elegans)]

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.

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364314 Nuclear hormone receptor 8 (C. Elegans)]

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. [http://partsregistry.org/wiki/index.php?title=Part:BBa_K364314 Go to the official parts registry page for this part]

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364315 Nuclear hormone receptor 23 (C. Elegans)]

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 [http://partsregistry.org/wiki/index.php?title=Part:BBa_K364315 Go to the official parts registry page for this part]

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364316 Nuclear hormone receptor 25 (C. Elegans)]

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.

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364317 Nuclear hormone receptor 31 (C. Elegans)]

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.

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364318 Nuclear hormone receptor 80 (C. Elegans)]

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 [http://partsregistry.org/wiki/index.php?title=Part:BBa_K364318 Go to the official parts registry page for this part]

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364306 Constitutive Androstane Receptor Ligand Binding Domain (H. Sapiens)]

The constitutive androstane receptor (CAR) also known as nuclear receptor subfamily 1, group I, member 3 is a protein that in humans is encoded by the NR1I3 gene.[1] CAR is a member of the nuclear receptor superfamily and along with PXR functions as a sensor of endobiotic and xenobiotic substances and in response upregulates the expression of proteins responsible for the metabolism and excretion of these substances.[2] Hence CAR (and PXR) are important in the detoxification of foreign substances such as drugs.

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K364308 Pregnane X receptor Ligand Binding Domain (H. Sapiens)]

PXR is a xenobiotic-activated member of the nuclear receptor superfamily of transcription factors. PXR is involved in transcriptional induction of hepatic xenobiotic-catabolizing cytochrome 3A enzymes, playing a fundamental role in protecting body tissues from toxic bile acids. PXR is almost exlcusively expressed in the gastrointestinal system (stomach, duodenum, jejunum, ileum, colon and gall bladder) and liver, with lower levels in the kidney and ovary. PXR dysfunction is associated with immune disorders (sclerosing cholangitis, inflammatory bowel disease) and biliary primary cirrhosis.

ER-α is a 17β-estradiol-activated steroid receptor member of the nuclear receptor superfamily of transcription factors. It has a variety of central physiological roles, including those involved in maintenance of the reproductive, cardiovascular, musculoskeletal and central nervous systems. ER-α is expressed at low to moderate levels in major physiological systems (central nervous system (CNS), endocrine, metabolic, gastrointestinal, immune, reproductive, cardiovascular, respiratory and structural), with peaks of expression in the pituitary, ovary, uterus and vas deferens. ER-α dysfunction is associated with cancer, cardiovascular system defects, hematological system defects, immune and inflammation diseases, metabolic defects, reproductive defects.
