gastrin-releasing peptide, human(tfa)

Gastrin-Releasing Peptide, human(TFA) is a regulatory human peptide that elicits gastrin release and regulates gastric acid secretion and enteric motor function. The post-ganglionic fibers of the vagus nerve that innervate the G cells of the stomach release GRP, which stimulates the G cells to release gastrin.

PACAP (1-38), human, ovine, rat TFA is an endogenous neuropeptide and a high-affinity agonist for the PAC1 receptor. This 38-amino acid peptide binds to the PAC1 receptor to activate adenylate cyclase, inducing an increase in intracellular cAMP levels and triggering downstream signaling. Research demonstrates that C-terminal amidation of PACAP (1-38), human, ovine, rat TFA is dispensable for its biological activity at the PAC1 receptor, with the non-amidated form retaining full agonistic potency. It plays crucial roles in neuroprotection, regulation of insulin secretion, and vasodilation.

Biotin-Gastrin Releasing Peptide, human TFA, is a biotinylated form of the gastrin-releasing peptide (GRP). GRP is a neuropeptide known for its growth-stimulating and tumorigenic properties.
