• Description: Growth Differentiation Factor 15 (GDF-15), also called Macrophage Inhibitory Cytokine 1 (MIC-1), Placental Transforming Growth Factor beta, Prostate-derived Factor, and Placental Bone Morphogenetic Protein, is a divergent member of the TGF-beta superfamily. Cellular responses to TGF-beta proteins are mediated by hetero-oligomeric complexes of type I and type II serine/threonine kinase receptors. GDF-15 is highly expressed in placenta and brain, and it is expressed at lower levels in kidney, pancreas, prostate, and colon. Similar to other TGF-beta family proteins, GDF-15 is synthesized as a large precursor protein that is cleaved at a dibasic cleavage site (RxxR) to release the mature protein. Mature mouse GDF-15 shares 66% and 97% amino acid sequence identity with the human and rat proteins, respectively. The C-terminal domain of GDF-15 contains seven characteristic conserved cysteine residues necessary for the formation of the cysteine knot and the single inter-chain disulfide bond. Biologically active GDF-15 is a disulfide-linked homodimer of the mature protein. GDF-15 has been shown to have various functions, including inhibition of TNF-alpha production from lipopolysaccharide-stimulated macrophages and the induction of cartilage formation. GDF-15 also promotes neuronal survival, and hypothalamic expression of GDF-15 causes appetite suppression via modulation of neuropeptide Y and pro-opiomelanocortin levels. GDF-15 is cardioprotective via inhibition of platelet activation, limiting atherosclerosis, promoting recovery following myocardial infarction, and regulating angiogenesis. Exposure of cardiomyocytes to GDF-15 results in Smad2 and Smad3 phosphorylation.
• Predicted N Terminal: Ser189
• Form: Lyophilized from a 0.2 μm filtered solution in HCl.
• Bio-activity: Measured by its binding ability in a functional ELISA. When Recombinant Mouse GSF-15 is immobilized at 2 µg/mL (100 µL/well), the concentration of Recombinant Mouse Activin RIB/ALK-4 Fc Chimera that produces 50% of the optimal binding response is approximately 1-6 μg/mL.
