Functional Studies - Recombinant human IGFBP3 protein (Active) (AB280941)

Fully biologically active determined by the dose dependent decrease in MCF7 cell proliferation.

ED₅₀ is 38.33 ng/ml, corresponding to a specific activity of 0.26 x 10⁵ units /mg.

Cell based assay testing is performed on the first lot of protein only and is provided as a reference for protein activity; subsequent lots of protein must pass all biophysical quality control parameters that meet the same parameters as the first lot.

機能

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 (PubMed : 10874028, PubMed : 19556345). Also exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R (PubMed : 20353938). Inhibits the positive effect of humanin on insulin sensitivity (PubMed : 19623253). Promotes testicular germ cell apoptosis (PubMed : 19952275). Acts via LRP-1/alpha2M receptor, also known as TGF-beta type V receptor, to mediate cell growth inhibition independent of IGF1 (PubMed : 9252371). Mechanistically, induces serine-specific dephosphorylation of IRS1 or IRS2 upon ligation to its receptor, leading to the inhibitory cascade (PubMed : 15371331). In the nucleus, interacts with transcription factors such as retinoid X receptor-alpha/RXRA to regulate transcriptional signaling and apoptosis (PubMed : 10874028).

翻訳後修飾

Phosphorylated by FAM20C in the extracellular medium. Phosphorylated by CK2; resulting in decreased nuclear localization (PubMed:19556345).
