Target

  • FunctionIGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
  • Tissue specificityExpressed by most tissues. Present in plasma.
  • Sequence similaritiesContains 1 IGFBP N-terminal domain.
    Contains 1 thyroglobulin type-1 domain.
  • Developmental stageIGFBP3 levels are higher during extrauterine life and peak during puberty.
  • DomainThe thyroglobulin type-1 domain mediates interaction with HN.
  • Post-translational
    modifications
    Phosphorylation sites are present in the extracelllular medium.
  • Cellular localizationSecreted.
