SKU:
STJP000459

Current Stock:
Host: CHO cells
Note: STRICTLY FOR FURTHER RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS.
Short Description: Recombinant-Human IGFBP-3-protein was developed from cho cells. For use in research applications.
Conjugation: Unconjugated
Formulation: Lyophilised from 0.2 Mu m filtered PBS solution.
Dilution Range: Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers.
Storage Instruction: Can be stored in working aliquots at 2°C-8°C C for one month, or at-20°C C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. NA
Endotoxin: Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). NA
Immunoreactivity: The ED (50) was determined by the ability toinhibit IGF-II induced proliferation of MCF-7 and was foundto be≤ 0.2 Mu g/ml in the presence of 15 ng/ml human IGF-II. NA
Gene Symbol: IGFBP3
Gene ID: 3486
Uniprot ID: IBP3_HUMAN
Immunogen Region: Mature chain
Immunogen: Optimized DNA sequence encoding HumanIGFBP-3 mature chain fused to an N-terminal His tag was expressed in CHO Cells. NA
Immunogen Sequence: NA
Tissue Specificity Expressed by most tissues. Present in plasma.
Post Translational Modifications Phosphorylated by FAM20C in the extracellular medium. Phosphorylated by CK2.resulting in decreased nuclear localization.
Function Multifunctional protein that plays a critical role in regulating the availability of IGFs such as IGF1 and IGF2 to their receptors and thereby regulates IGF-mediated cellular processes including proliferation, differentiation, and apoptosis in a cell-type specific manner. Also exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R. Inhibits the positive effect of humanin on insulin sensitivity. Promotes testicular germ cell apoptosis. Acts via LRP-1/alpha2M receptor, also known as TGF-beta type V receptor, to mediate cell growth inhibition independent of IGF1. Mechanistically, induces serine-specific dephosphorylation of IRS1 or IRS2 upon ligation to its receptor, leading to the inhibitory cascade. In the nucleus, interacts with transcription factors such as retinoid X receptor-alpha/RXRA to regulate transcriptional signaling and apoptosis.
