  • Entrez GeneID:
  • 3487
  • Gene Name:
  • IGFBP4
  • Gene Alias:
  • BP-4,HT29-IGFBP,IBP4,IGFBP-4
  • Gene Description:
  • insulin-like growth factor binding protein 4
  • Gene Summary:
  • This gene is a member of the insulin-like growth factor binding protein (IGFBP) family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein binds both insulin-like growth factors (IGFs) I and II and circulates in the plasma in both glycosylated and non-glycosylated forms. Binding of this protein prolongs the half-life of the IGFs and alters their interaction with cell surface receptors. [provided by RefSeq
