1.MECHANISM OF ACTION

Growth Hormone Releasing Factor, GRF (1-40), amide, human binds with high affinity to GHRH receptors on pituitary somatotroph cells, activating G-protein coupled signaling pathways. This binding stimulates adenylate cyclase activity, increasing intracellular cAMP levels and activating protein kinase A (PKA). The downstream effects include phosphorylation of transcription factors (such as CREB), enhanced growth hormone gene expression, and stimulation of growth hormone synthesis and secretion. The C-terminal amidation enhances peptide stability and receptor binding affinity, while the human sequence ensures optimal activity in human cell-based systems and translational research models.
