Summary: Enables several functions, including core promoter sequence-specific DNA binding activity; nuclear receptor activity; and protein heterodimerization activity. Contributes to DNA-binding transcription activator activity, RNA polymerase II-specific and ecdysone binding activity. Involved in several processes, including border follicle cell migration; instar larval or pupal development; and nervous system development. Located in dendrite and nucleus. Part of activator ecdysone receptor complex. Is expressed in several structures, including adult cuticle; central nervous system; female germline cell; gland; and imaginal disc. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma and pancreatic cancer. Orthologous to human RXRA (retinoid X receptor alpha); RXRB (retinoid X receptor beta); and RXRG (retinoid X receptor gamma). [provided by Alliance of Genome Resources, Nov 2024]

Context-dependent functional properties of EcR and USP receptors in Drosophila cell survival.
Title: Ligand-independent requirements of steroid receptors EcR and USP for cell survival.
nutrition controls ecdysone biosynthesis partially via FoxO-Usp prior to critical weight, ensuring that growth only stops once larvae have achieved a target nutritional status.
Title: Nutritional control of body size through FoxO-Ultraspiracle mediated ecdysone biosynthesis.
The results suggest that normal larval to pupal maturation in this mecopteran model insect requires the involvement of a distinct endocrine axis of USP binding to its own endogenous terpenoid ligand.
Title: Ligand binding pocket function of Drosophila USP is necessary for metamorphosis.
PKC mediates USP phosphorylation at Ser35 in Kc and S2 cells, which regulates 20-hydroxyecdysone signaling.
Title: PKC-mediated USP phosphorylation at Ser35 modulates 20-hydroxyecdysone signaling in Drosophila.
sumoylation of Usp protein can be an important factor in modulating its activity by changing molecular interactions
Title: Alternative sumoylation sites in the Drosophila nuclear receptor Usp.
Ecdysone and NO mediate gene regulation by competing EcR/Usp and E75A nuclear receptors during Drosophila development
Title: Ecdysone- and NO-mediated gene regulation by competing EcR/Usp and E75A nuclear receptors during Drosophila development.
Ecdysone receptor and USP were expressed in numerous adult tissues, but receptor activity varied depending on tissue type and adult age. Receptor activity is reduced when a constitutively inactive ecdysone receptor is present.
Title: Ecdysone receptor expression and activity in adult Drosophila melanogaster.
Data show that ultraspiracle- and ecdysteroid receptor-mediated transcriptional activity not only depends on an interaction between the ecdysteroid receptor and a given hormone response element, but is also modified by surrounding DNA sequences.
Title: The N-terminus of ecdysteroid receptor isoforms and ultraspiracle interacts with different ecdysteroid response elements in a sequence specific manner to modulate transcriptional activity.
stability of the ecdysone receptor (EcR) is regulated in a cooperative manner by the AB-domains of EcR and Ultraspiracle
Title: Transcriptional activity of ecdysone receptor isoforms is regulated by modulation of receptor stability and interaction with Ab- and C-domains of the heterodimerization partner ultraspiracle.
The heterodimerization partner Usp increased DNA binding of ecdysone receptor considerably
