Chain A,B   (OB76A_DROME | O02372)
molecular function
    GO:0035275    dibutyl phthalate binding    Interacting selectively and non-covalently with dibutyl phthalate, C(16)H(22)O(4).
    GO:0035274    diphenyl phthalate binding    Interacting selectively and non-covalently with diphenyl phthalate, C(20)H(14)O(4).
    GO:0035276    ethanol binding    Interacting selectively and non-covalently with ethanol, CH(3)-CH(2)-OH.
    GO:0005549    odorant binding    Interacting selectively and non-covalently with an odorant, any substance capable of stimulating the sense of smell.
    GO:0005550    pheromone binding    Interacting selectively and non-covalently with a pheromone, a substance, or characteristic mixture of substances, that is secreted and released by an organism and detected by a second organism of the same or a closely related species, in which it causes a specific reaction, such as a definite behavioral reaction or a developmental process.
biological process
    GO:0007610    behavior    The internally coordinated responses (actions or inactions) of animals (individuals or groups) to internal or external stimuli, via a mechanism that involves nervous system activity.
    GO:0007619    courtship behavior    The behavioral interactions between organisms for the purpose of attracting sexual partners.
    GO:0042048    olfactory behavior    The behavior of an organism in response to an odor.
    GO:0045471    response to ethanol    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 an ethanol stimulus.
    GO:0019236    response to pheromone    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 pheromone stimulus.
    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:0007606    sensory perception of chemical stimulus    The series of events required for an organism to receive a sensory chemical stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process.
    GO:0007608    sensory perception of smell    The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors. This is a neurological process.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
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.
