Insulin-like growth factor-binding protein 3 (IGFBP-3)

Target (abbrv.) IGFBP-3
Target (full name) Insulin-like growth factor-binding protein 3
Somalogic ID (Sequence ID) SL000045 (2571-12_3)
Entrez Gene Symbol IGFBP3
UniProt ID P17936
UniProt Comment
  • 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. Also exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R.

UniProt ID P05019
UniProt Comment
  • The insulin-like growth factors, isolated from plasma, are structurally and functionally related to insulin but have a much higher growth-promoting activity. May be a physiological regulator of [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblasts. Stimulates glucose transport in bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regard to enhancing glucose uptake. May play a role in synapse maturation (PubMed:21076856, PubMed:24132240). Ca(2+)-dependent exocytosis of IGF1 is required for sensory perception of smell in the olfactory bulb (By similarity).

All locus annotations are based on the sentinel SNP (rs2949833) and 1 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.

Functional match between insulin-like growth factor-binding protein in cis and insulin-like growth factor in trans.

This locus harbours a replicated cis-association with insulin-like growth factor-binding protein 3 (IGFBP3) levels. A trans-association with insulin-like growth factor I (IGF1) levels was only nominal in QMDiab (p=5.1×10-3). Both associations display the same directionality. This locus replicates Kaplan et al. [PubMed] association of SNP rs11977526 (chr7:46008110) (IGFBP3) with IGF-I levels. Confirms strong GWAS hits.

The information gathered here is a result of an attempt to keep track of all interesting information that we encountered while investigating these loci. Please bear in mind that the annotation given here is neither complete nor free of errors, and that all information provided here should be confirmed by additional literature research before being used as a basis for firm conclusions or further experiments.
