  • 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
      Phosphorylation sites are present in the extracelllular medium.
    • Cellular localizationSecreted.

    • ab36529 staining human fibroblast cells by ICC/IF.  Cells were fixed in formaldehyde, permeabilised in 0.5% triton for 5 min, and blocked with 4% BSA for 1 hour at 20°C.  The primary antibody was diluted 1/200 with 4% BSA/TBST and incubated for 2 hours at 20°C.  An Alexa Fluor® 594 conjugated donkey anti-mouse was used as the secondary antibody.

      Red fluorescence shows IGFBP3, blue is DNA.
