1.MECHANISM OF ACTION
Growth Hormone Releasing Factor, GRF (1-44), amide, bovine 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 bovine sequence exhibits cross-reactivity with multiple species' GHRH receptors, making it valuable for comparative endocrine studies.
