Target
-
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
modificationsPhosphorylation sites are present in the extracelllular medium. -
Cellular localization

Predicted band size: 32 kDa
Observed band size: 28 kDa why is the actual band size different from the predicted?
Additional bands at: 50 kDa (possible non-specific binding)
The additional band of 50 kDa was consistently observed. However this band was not blocked by the immunizing peptide and it is therefore a non specific signal.
