Gene Information

human ... IGFBP5(3488)

General description

The gene IGFBP-5 (insulin-like growth factor binding protein-5) is mapped to human chromosome 2q35.

Biochem/physiol Actions

IGFBP-5 (insulin-like growth factor binding protein-5) interacts with IGFs and thereby controls IGF activity. High levels of IGFBP5 are present in systemic sclerosis and idiopathic pulmonary fibrosis conditions. It also plays a crucial role in cancer progression.
IGFBP-5 binds to bone cells and is the predominant insulin-like growth factor binding protein in bone. When IGFBP-5 binds the extracellular matrix, it modulates IGF activity. Mouse, human, and rat IGFBP-5 share 97% homology.

Physical form

Lyophilized from a 0.2 μm filtered solution in 30% acetonitrile and 0.1% TFA.

Analysis Note

The biological activity is measured by its ability to inhibit recombinant human IGF-1 or IGF-II on MCF-7 cells.

Over the last decade, the concept of an IGFBP family has been well accepted, based on structural similarities and on functional abilities to bind IGFs with high affinities. The existence of other potential IGFBPs was left open. The discovery of

Insulin-like growth factor binding protein (IGFBP)-5 levels are increased in systemic sclerosis (SSc) skin and lung. We previously reported that IGFBP-5 is a pro-fibrotic factor that induces extracellular matrix (ECM) production and deposition. Since IGFBP-5 contains a nuclear localization signal

GWAS have identified a breast cancer susceptibility locus on 2q35. Here we report the fine mapping of this locus using data from 101,943 subjects from 50 case-control studies. We genotype 276 SNPs using the 'iCOGS' genotyping array and impute genotypes

RASSF1C is a major isoform of the RASSF1 gene, and is emerging as an oncogene. This is in contradistinction to the RASSF1A isoform, which is an established tumor suppressor. We have previously shown that RASSF1C promotes lung cancer cell proliferation
