Chain Q,X   (A8Y5F6_MOUSE | A8Y5F6)
cellular component
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

Chain Q,X   (PDPN_MOUSE | Q62011)
molecular function
    GO:0015171    amino acid transmembrane transporter activity    Enables the transfer of amino acids from one side of a membrane to the other. Amino acids are organic molecules that contain an amino group and a carboxyl group.
    GO:0008517    folic acid transporter activity    Enables the directed movement of folic acid (pteroylglutamic acid) into, out of or within a cell, or between cells. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines.
    GO:0015250    water channel activity    Transport systems of this type enable facilitated diffusion of water (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
    GO:0005372    water transmembrane transporter activity    Enables the directed movement of water (H2O) from one side of a membrane to the other.
biological process
    GO:0006865    amino acid transport    The directed movement of amino acids, organic acids containing one or more amino substituents, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0007155    cell adhesion    The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.
    GO:0000902    cell morphogenesis    The developmental process in which the size or shape of a cell is generated and organized.
    GO:0048870    cell motility    Any process involved in the controlled self-propelled movement of a cell that results in translocation of the cell from one place to another.
    GO:0008283    cell proliferation    The multiplication or reproduction of cells, resulting in the expansion of a cell population.
    GO:0015884    folic acid transport    The directed movement of folic acid (pteroylglutamic acid) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines.
    GO:0048286    lung alveolus development    The process whose specific outcome is the progression of the alveolus over time, from its formation to the mature structure. The alveolus is a sac for holding air in the lungs; formed by the terminal dilation of air passageways.
    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:0001946    lymphangiogenesis    Lymph vessel formation when new vessels emerge from the proliferation of pre-existing vessels.
    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:0030335    positive regulation of cell migration    Any process that activates or increases the frequency, rate or extent of cell migration.
    GO:0051272    positive regulation of cellular component movement    Any process that activates or increases the frequency, rate or extent of the movement of a cellular component.
    GO:0006693    prostaglandin metabolic process    The chemical reactions and pathways involving prostaglandins, any of a group of biologically active metabolites which contain a cyclopentane ring due to the formation of a bond between two carbons of a fatty acid. They have a wide range of biological activities.
    GO:2000045    regulation of G1/S transition of mitotic cell cycle    Any cell cycle regulatory process that controls the commitment of a cell from G1 to S phase of the mitotic cell cycle.
    GO:0008360    regulation of cell shape    Any process that modulates the surface configuration of a cell.
    GO:0007165    signal transduction    The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
    GO:0016337    single organismal cell-cell adhesion    The attachment of one cell to another cell via adhesion molecules, where both cells are part of the same organism.
    GO:0035239    tube morphogenesis    The process in which the anatomical structures of a tube are generated and organized. Epithelial and endothelial tubes transport gases, liquids and cells from one site to another and form the basic structure of many organs and tissues, with tube shape and organization varying from the single-celled excretory organ in Caenorhabditis elegans to the branching trees of the mammalian kidney and insect tracheal system.
    GO:0061032    visceral serous pericardium development    The progression of the visceral serous pericardium from its formation to the mature structure. The visceral serous pericardium is the inner layer of the pericardium.
    GO:0006833    water transport    The directed movement of water (H2O) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
cellular component
    GO:0042995    cell projection    A prolongation or process extending from a cell, e.g. a flagellum or axon.
    GO:0009897    external side of plasma membrane    The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
    GO:0030175    filopodium    Thin, stiff, actin-based protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal or dendritic growth cone, or a dendritic shaft.
    GO:0031527    filopodium membrane    The portion of the plasma membrane surrounding a filopodium.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0030027    lamellipodium    A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments.
    GO:0031258    lamellipodium membrane    The portion of the plasma membrane surrounding a lamellipodium.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0031528    microvillus membrane    The portion of the plasma membrane surrounding a microvillus.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
    GO:0001726    ruffle    Projection at the leading edge of a crawling cell; the protrusions are supported by a microfilament meshwork.
    GO:0032587    ruffle membrane    The portion of the plasma membrane surrounding a ruffle.
