Description | RecName: Ecdysone receptor;Alternative Name: Ecdysteroid receptor;Alternative Name: 20-hydroxy-ecdysone receptor;20E receptor;Alternative Name: EcRH;Alternative Name: Nuclear receptor subfamily 1 group H member 1; |
Source organism | Drosophila melanogaster (Fruit fly) |
Taxonomical Classification | Eukaryota; Metazoa; Arthropoda; Hexapoda; Insecta; Pterygota;Neoptera; Endopterygota; Diptera; Brachycera; Muscomorpha;Ephydroidea; Drosophilidae; Drosophila; Sophophora. |
Subcellular location | Nucleus |
Developmental Stage | In the salivary glands of mid instar larvae levels increase during puff stage 1 at 86-94 hours of development then remain relatively constant until the premetamorphic pulse of ecdysone in late larvae. Levels diminish dramatically from puff stage 7 onwards. Levels increase in the prepupal period during puff stage 13-14, the level remains stable until stage 21. A decrease in levels at puff stage 7 is also seen in the Malpighian tubules and less dramatically in the fat body and gut. In the wing disk the relatively low level remains unchanged. |
Similarity | Belongs to the nuclear hormone receptor family. NR1 subfamily. Contains 1 nuclear receptor DNA-binding domain. |
Tissue Specificity | Isoform B1 predominates over isoform A in larval tissues, imaginal histoblast nests and midgut islands. Isoform A predominates over B1 in imaginal disks, and the larval prothoracic gland. |
Post translational modification | N/A |
Function | Receptor for ecdysone. Binds to ecdysone response elements (ECRES) following ecdysone-binding, and recruitment of a complex containing the histone methyltransferase trr, leads to activate transcription of target genes. |
