Chain A   (RET4_HUMAN | P02753)
molecular function
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0046982    protein heterodimerization activity    Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
    GO:0016918    retinal binding    Interacting selectively and non-covalently with retinal, one of the forms of vitamin A. Retinal plays an important role in the visual process in most vertebrates, combining with opsins to form visual pigments in the retina.
    GO:0005501    retinoid binding    Interacting selectively and non-covalently with retinoids, any member of a class of isoprenoids that contain or are derived from four prenyl groups linked head-to-tail. Retinoids include retinol and retinal and structurally similar natural derivatives or synthetic compounds, but need not have vitamin A activity.
    GO:0019841    retinol binding    Interacting selectively and non-covalently with retinol, vitamin A1, 2,6,6-trimethyl-1-(9'-hydroxy-3',7'-dimethylnona-1',3',5',7'-tetraenyl)cyclohex-1-ene, one of the three components that makes up vitamin A. Retinol is an intermediate in the vision cycle and it also plays a role in growth and differentiation.
    GO:0034632    retinol transporter activity    Enables the directed movement of retinol into, out of or within a cell, or between cells. Retinol is vitamin A1, 2,6,6-trimethyl-1-(9'-hydroxy-3',7'-dimethylnona-1',3',5',7'-tetraenyl)cyclohex-1-ene, one of the three components that makes up vitamin A.
    GO:0036094    small molecule binding    Interacting selectively and non-covalently with a small molecule, any low molecular weight, monomeric, non-encoded molecule.
    GO:0005215    transporter activity    Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
biological process
    GO:0048738    cardiac muscle tissue development    The process whose specific outcome is the progression of cardiac muscle over time, from its formation to the mature structure.
    GO:0048562    embryonic organ morphogenesis    Morphogenesis, during the embryonic phase, of a tissue or tissues that work together to perform a specific function or functions. Morphogenesis is the process in which anatomical structures are generated and organized. Organs are commonly observed as visibly distinct structures, but may also exist as loosely associated clusters of cells that work together to perform a specific function or functions.
    GO:0060059    embryonic retina morphogenesis in camera-type eye    The process in which the anatomical structure of the retina is generated and organized in a camera-type eye during the embryonic life stage.
    GO:0048706    embryonic skeletal system development    The process, occurring during the embryonic phase, whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure.
    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:0048807    female genitalia morphogenesis    The process in which the anatomical structures of female genitalia are generated and organized.
    GO:0006094    gluconeogenesis    The formation of glucose from noncarbohydrate precursors, such as pyruvate, amino acids and glycerol.
    GO:0042593    glucose homeostasis    Any process involved in the maintenance of an internal steady state of glucose within an organism or cell.
    GO:0007507    heart development    The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.
    GO:0060347    heart trabecula formation    The process of creating a trabecula in the heart. A trabecula is a tissue element in the form of a small beam, strut or rod.
    GO:0030324    lung development    The process whose specific outcome is the progression of the lung over time, from its formation to the mature structure. In all air-breathing vertebrates the lungs are developed from the ventral wall of the oesophagus as a pouch which divides into two sacs. In amphibians and many reptiles the lungs retain very nearly this primitive sac-like character, but in the higher forms the connection with the esophagus becomes elongated into the windpipe and the inner walls of the sacs become more and more divided, until, in the mammals, the air spaces become minutely divided into tubes ending in small air cells, in the walls of which the blood circulates in a fine network of capillaries. In mammals the lungs are more or less divided into lobes, and each lung occupies a separate cavity in the thorax.
    GO:0030277    maintenance of gastrointestinal epithelium    Protection of epithelial surfaces of the gastrointestinal tract from proteolytic and caustic digestive agents.
    GO:0060044    negative regulation of cardiac muscle cell proliferation    Any process that stops, prevents, or reduces the frequency, rate or extent of cardiac muscle cell proliferation.
    GO:0051024    positive regulation of immunoglobulin secretion    Any process that activates or increases the frequency, rate or extent of the regulated release of immunoglobulins from a cell.
    GO:0032024    positive regulation of insulin secretion    Any process that activates or increases the frequency, rate or extent of the regulated release of insulin.
    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:0032526    response to retinoic acid    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 retinoic acid 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:0001523    retinoid metabolic process    The chemical reactions and pathways involving retinoids, any member of a class of isoprenoids that contain or are derived from four prenyl groups linked head-to-tail. Retinoids include retinol and retinal and structurally similar natural derivatives or synthetic compounds, but need not have vitamin A activity.
    GO:0042572    retinol metabolic process    The chemical reactions and pathways involving retinol, one of the three compounds that makes up vitamin A.
    GO:0034633    retinol transport    The directed movement of retinol into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Retinol is vitamin A1, 2,6,6-trimethyl-1-(9'-hydroxy-3',7'-dimethylnona-1',3',5',7'-tetraenyl)cyclohex-1-ene, one of the three components that makes up vitamin A.
    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.
    GO:0060157    urinary bladder development    The process whose specific outcome is the progression of the urinary bladder over time, from its formation to the mature structure. The urinary bladder is an elastic, muscular sac situated in the anterior part of the pelvic cavity in which urine collects before excretion.
    GO:0060065    uterus development    The reproductive developmental process whose specific outcome is the progression of the uterus over time, from its formation to the mature structure.
    GO:0060068    vagina development    The reproductive developmental process whose specific outcome is the progression of the vagina over time, from its formation to the mature structure.
    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.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    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.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
    GO:0043234    protein complex    A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.
