  • Function
    IGF-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 specificity
    Expressed by most tissues. Present in plasma.
  • Sequence similarities
    Contains 1 IGFBP N-terminal domain.
    Contains 1 thyroglobulin type-1 domain.
  • Developmental stage
    IGFBP3 levels are higher during extrauterine life and peak during puberty.
  • Domain
    The thyroglobulin type-1 domain mediates interaction with HN.
  • Post-translational
    Phosphorylation sites are present in the extracelllular medium.
