Chain A,B   (SHPS1_HUMAN | P78324)
molecular function
    GO:0017124    SH3 domain binding    Interacting selectively and non-covalently with a SH3 domain (Src homology 3) of a protein, small protein modules containing approximately 50 amino acid residues found in a great variety of intracellular or membrane-associated proteins.
biological process
    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:0050900    leukocyte migration    The movement of a leukocyte within or between different tissues and organs of the body.
cellular component
    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: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.
    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.

Chain C,D   (CD47_HUMAN | Q08722)
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:0070053    thrombospondin receptor activity    Combining with thrombospondin and transmitting the signal to initiate a change in cell activity.
biological process
    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:0030198    extracellular matrix organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.
    GO:0007229    integrin-mediated signaling pathway    A series of molecular signals initiated by the binding of extracellular ligand to an integrin on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.
    GO:0050900    leukocyte migration    The movement of a leukocyte within or between different tissues and organs of the body.
    GO:0008228    opsonization    The process in which a microorganism (or other particulate material) is rendered more susceptible to phagocytosis by coating with an opsonin, a blood serum protein such as a complement component or antibody.
    GO:0050870    positive regulation of T cell activation    Any process that activates or increases the frequency, rate or extent of T cell activation.
    GO:0008284    positive regulation of cell proliferation    Any process that activates or increases the rate or extent of cell proliferation.
    GO:0022409    positive regulation of cell-cell adhesion    Any process that activates or increases the rate or extent of cell adhesion to another cell.
    GO:0050729    positive regulation of inflammatory response    Any process that activates or increases the frequency, rate or extent of the inflammatory response.
    GO:0050766    positive regulation of phagocytosis    Any process that activates or increases the frequency, rate or extent of phagocytosis.
    GO:0009617    response to bacterium    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 from a bacterium.
cellular component
    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.
