GDF-15 Protein, Human (Biotinylated, His-Avi)

GDF-15 Protein is central to regulating food intake, energy expenditure, and body weight in response to metabolic and toxin-induced stresses. It binds to its receptor, GFRAL, activating GFRAL-expressing neurons in the brainstem. This triggers the activation of neurons in the parabrachial nucleus and central amygdala, shaping feeding responses during stress. Moreover, GDF-15 inhibits growth hormone signaling on hepatocytes and acts as a ligand for RET, mediating cellular signaling through GDF15 internalization. GDF-15 Protein, Human (Biotinylated, His-Avi) is the recombinant human-derived GDF-15 protein, expressed by E. coli, with C-Avi, N-His labeled tag. The total length of GDF-15 Protein, Human (Biotinylated, His-Avi) is 112 a.a., with molecular weight of 15.19 kDa.

GDF-15 Protein plays a pivotal role in regulating food intake, energy expenditure, and body weight in response to metabolic and toxin-induced stresses. It exerts its effects by binding to its receptor, GFRAL, and activating GFRAL-expressing neurons in the area postrema and nucleus tractus solitarius of the brainstem. This activation subsequently triggers the activation of neurons in the parabrachial nucleus and central amygdala, forming part of the 'emergency circuit' involved in shaping feeding responses during stressful conditions. Additionally, GDF-15 Protein inhibits growth hormone signaling on hepatocytes. It exists as a homodimer and interacts with GFRAL, acting as a ligand that mediates GDF15 internalization and cellular signaling through interaction with RET.
