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 modifications Phosphorylation sites are present in the extracelllular medium.
Cellular localization Secreted.
Information by UniProt
