Asymmetric Unit(hide GO term definitions)
Chain A,B   (GIL_DROME | Q00805)
molecular function
    GO:0005154    epidermal growth factor receptor binding    Interacting selectively and non-covalently with the epidermal growth factor receptor.
    GO:0048019    receptor antagonist activity    Interacts with receptors to reduce the action of another ligand, the agonist.
biological process
    GO:0007411    axon guidance    The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.
    GO:0042067    establishment of ommatidial planar polarity    The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part.
    GO:1900116    extracellular negative regulation of signal transduction    Any negative regulation of signal transduction that takes place in extracellular region.
    GO:0001654    eye development    The process whose specific outcome is the progression of the eye over time, from its formation to the mature structure. The eye is the organ of sight.
    GO:0007455    eye-antennal disc morphogenesis    The process in which the anatomical structures derived from the eye-antennal disc are generated and organized. This includes the transformation of an eye-antennal imaginal disc from a monolayered epithelium in the larvae of holometabolous insects into recognizable adult structures including the eye, antenna, head capsule and maxillary palps.
    GO:0035215    genital disc development    Progression of the genital imaginal disc over time, from its initial formation through to its metamorphosis to form the adult terminalia, comprising the entire set of internal and external genitalia and analia. Both sexes of Drosophila have a single genital disc formed from the female and male genital primordia, and the anal primordium. The anal primordium develops in both sexes, forming either male or female analia. However, only one of the genital primordia develops in each sex, forming either the male or the female genitalia.
    GO:0007482    haltere development    The process whose specific outcome is the progression of the haltere over time, from its formation to the mature structure. The haltere is the club-shaped 'balancers' found on each side of the metathorax among the true flies (Diptera). They are the much-modified hind wings.
    GO:0007476    imaginal disc-derived wing morphogenesis    The process in which the anatomical structures of the imaginal disc-derived wing are generated and organized. The wing is an appendage modified for flying.
    GO:0007474    imaginal disc-derived wing vein specification    The regionalization process in which the area of a imaginal disc-derived wing that will form a wing vein is specified.
    GO:0046331    lateral inhibition    Signaling between cells of equivalent developmental potential that results in these cells adopting different developmental fates. An example is the suppression by cells with a particular fate of the adoption of the same fate by surrounding cells.
    GO:0007275    multicellular organism development    The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
    GO:0045596    negative regulation of cell differentiation    Any process that stops, prevents, or reduces the frequency, rate or extent of cell differentiation.
    GO:0009996    negative regulation of cell fate specification    Any process that restricts, stops or prevents a cell from adopting a specific cell fate.
    GO:0042059    negative regulation of epidermal growth factor receptor signaling pathway    Any process that stops, prevents, or reduces the frequency, rate or extent of epidermal growth factor receptor signaling pathway activity.
    GO:0050768    negative regulation of neurogenesis    Any process that stops, prevents, or reduces the frequency, rate or extent of neurogenesis, the origin and formation of neurons.
    GO:2000737    negative regulation of stem cell differentiation    Any process that stops, prevents or reduces the frequency, rate or extent of stem cell differentiation.
    GO:0060233    oenocyte delamination    The negative regulation of cell adhesion process in which an oenocyte splits off of an existing epithelial sheet.
    GO:0016318    ommatidial rotation    The process in which photoreceptors are arranged in ommatidia in the dorsal and ventral fields to be mirror images. The polarity is established in the imaginal discs concurrently with cell fate specification.
    GO:0030707    ovarian follicle cell development    The process that occurs during oogenesis involving the ovarian follicle cells, somatic cells which surround the germ cells of an ovary. An example of this is found in Drosophila melanogaster.
    GO:0043065    positive regulation of apoptotic process    Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process.
    GO:0050896    response to stimulus    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism.
    GO:0007601    visual perception    The series of events required for an organism to receive a visual stimulus, convert it to a molecular signal, and recognize and characterize the signal. Visual stimuli are detected in the form of photons and are processed to form an image.
    GO:0007472    wing disc morphogenesis    The process in which the anatomical structures derived from the wing disc are generated and organized. This includes the transformation of a wing imaginal disc from a monolayered epithelium in the larvae of holometabolous insects into recognizable adult structures including the wing hinge, wing blade and pleura.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
