IGFBP-3 Protein, Cynomolgus (HEK293, His)

IGFBP-3 Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived IGFBP-3 protein, expressed by HEK293, with N-His tag.

IGFBP-3 Protein, a member of the insulin-like growth factor-binding proteins (IGFBPs), plays a crucial role in extending the half-life of insulin-like growth factors (IGFs) and modulating their growth-promoting effects on cell culture. With the capacity to either inhibit or stimulate IGF-induced cellular responses, IGFBP-3 exerts its regulatory influence by altering the interaction dynamics between IGFs and their respective cell surface receptors. Additionally, IGFBP-3 exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R. Furthermore, IGFBP-3 inhibits the positive effect of humanin on insulin sensitivity and promotes testicular germ cell apoptosis. Interactions with XLKD1 and the formation of a ternary complex with IGF1 or IGF2 and a glycoprotein (ALS) further underscore the diverse roles of IGFBP-3. The intricate network of interactions, including those with humanin and TMEM219, highlights the multifaceted nature of IGFBP-3 in modulating cellular processes and signaling pathways associated with growth and apoptosis.
