IGFBP3 - insulin like growth factor binding protein 3 Gene
Also Known as IBP3; BP-53
Species: Homo sapiens
About IGFBP3
This gene has 9 transcripts (splice variants), 264 orthologues and 5 paralogues. Biased expression in placenta (RPKM 686.3), endometrium (RPKM 259.6) and 7 other tissues.
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 forms a ternary complex with insulin-like growth factor acid-labile subunit (IGFALS) and either insulin-like growth factor (IGF) I or II. In this form, it circulates in the plasma, prolonging the half-life of IGFs and altering their interaction with cell surface receptors. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
