cellular component
    GO:0008232    activator ecdysone receptor complex    A protein complex consisting of a heterodimer of Ecdysone receptor (EcR) and ultraspiracle (usp) bound to the ligand ecdysone, which activates transcription of target genes.
    GO:0030425    dendrite    A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
    GO:0008230    ecdysone receptor holocomplex    A heterodimeric complex containing the products of the insect genes Ecdysone receptor (EcR) and ultraspiracle (usp). Binding of ecdysone promotes association between the two subunits, and the receptor complex then initiates molting and metamorphosis by binding DNA and regulating the transcription of target genes.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing.

    GO:0005700    polytene chromosome    A type of chromosome in a polyploid cell, formed when multiple copies of homologous chromosomes are aligned side by side to give a giant chromosome in which distinct chromosome bands are readily visible.

    GO:0004879    RNA polymerase II transcription factor activity, ligand-activated sequence-specific DNA binding    Combining with a signal and transmitting the signal to the transcriptional machinery by interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription by RNA polymerase II.
    GO:0001047    core promoter binding    Interacting selectively and non-covalently with the regulatory region composed of the transcription start site and binding sites for the basal transcription machinery.
