Asymmetric Unit(hide GO term definitions)
Chain A,B,C,D   (SIBD1_CUPSA | G4V4F9)
molecular function
    GO:0005520    insulin-like growth factor binding    Interacting selectively and non-covalently with an insulin-like growth factor, any member of a group of polypeptides that are structurally homologous to insulin and share many of its biological activities, but are immunologically distinct from it.
biological process
    GO:0002376    immune system process    Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
    GO:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
    GO:0001558    regulation of cell growth    Any process that modulates the frequency, rate, extent or direction of cell growth.
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.
