生物活性
Measured by its ability to inhibit the biological activity of IGF-II (rp147265) on MCF‑7 human breast cancer cells. The ED50 for this effect is 1.68 µg/mL in the presence of 14 ng/mL rhIGF-II.
Multifunctional protein that plays a critical role in regulating the availability of IGFs to their receptors and thereby regulates IGF-mediated cellular processes including proliferation, differentiation, and apoptosis in a cell-type specific manner (PubMed:18930415, PubMed:7683690).
Increases the cell proliferation of osteoblasts, intestinal smooth muscle cells and neuroblastoma cells. Enhances adhesion and survival of epithelial cells but decreases adhesion of mesenchymal cells (By similarity).
Once secreted, acts as a major mediator of mTORC1-dependent feedback inhibition of IGF1 signaling (By similarity).
Also plays a role in the induction of extracellular matrix (ECM) production and deposition independently of its nuclear translocation and binding to IGFs (PubMed:20345844, PubMed:26103640).
Acts itself as a growth factor that can act independently of IGFs to regulate bone formation. Acts as a ligand for the ROR1 receptor which triggers formation of ROR1/HER2 heterodimer to enhance CREB oncogenic signaling (PubMed:36949068).
Post-translational: Cleaved by C1S in extracellular space.

Recombinant Human IGFBP5 Protein (rp222575) - Protein Bioactivity
Measured by its ability to inhibit the biological activity of IGF-II (rp147265) on MCF‑7 human breast cancer cells. The ED50 for this effect is 1.68 µg/mL in the presence of 14 ng/mL rhIGF-II.
Recombinant Human IGFBP5 Protein (rp222575) - SDS-PAGE
3 μg/lane of Recombinant Human IGFBP5 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the band at 30.1-35.5 kDa under reducing conditions and 29.2-34.9 kDa under non-reducing conditions.
