β-Lipotropin (61-64)

β-Lipotropin (61-64) is a high-purity synthetic tetrapeptide corresponding to the 61-64 amino acid fragment of human β-lipotropin, with the sequence Tyr-Gly-Gly-Phe (YGGF). This peptide represents the core sequence of methionine-enkephalin, an endogenous opioid peptide that plays a crucial role in pain modulation, stress response, and neuroendocrine regulation. Manufactured under stringent quality controls with HPLC-verified purity and comprehensive analytical documentation, this peptide provides researchers with a precise tool for studying opioid receptor interactions, neuropeptide signaling, and analgesic mechanisms. Its short sequence and well-characterized biological activity make it ideal for receptor binding studies, structure-activity relationship research, and neuropharmacology applications

1.MECHANISM OF ACTION

β-Lipotropin (61-64) functions as an endogenous opioid peptide that binds to and activates μ-opioid and δ-opioid receptors in the central and peripheral nervous systems. Upon receptor binding, it triggers G-protein coupled signaling pathways, leading to inhibition of adenylate cyclase activity, reduction of intracellular cAMP levels, and modulation of ion channel activity (particularly potassium channel activation and calcium channel inhibition). These molecular events result in decreased neurotransmitter release, hyperpolarization of neurons, and inhibition of pain signal transmission. The peptide's Tyr-Gly-Gly-Phe sequence constitutes the conserved opioid motif essential for receptor recognition and activation. Its short length allows for precise investigation of structure-activity relationships and receptor binding domains without interference from larger peptide regions.
