tip 39 peptide selectively activates the PTH2 receptor

Published October Oct 18, 2026 12:16 AM

In the specialized field of biochemical research, the Tip 39 peptide—formally known as the tuberoinfundibular peptide of 39 residues (TIP39)—represents a fascinating area of study. As someone deeply engaged in the observation of peptide science, I have found that understanding the nuances of this specific molecule requires looking closely at its origins, its structural classification, and its unique interaction with biological receptors.

Origins and Structural Classification

The TIP 39 molecule is a remarkable neuropeptide. It was first identified from the bovine hypothalamus and is recognized as a small peptide belonging to the PTH-related family, which also includes parathyroid hormone (PTH) and parathyroid hormone-related peptide (PTHrP).

From a genetic perspective, it is a protein that in humans is encoded by the PTH2 gene. This gene acts as the precursor of a peptide hormone that shares sequence similarity with PT Buy Tip39 Peptide for Sale Online H. Since it was first extracted in 1997, it has remained a focal point for those interested in the complexitie Background The tuberoinfundibular peptide of 39 residues (TIP39) is a small peptide first extracted in 1997, which has garnered limited research attention. s of the central nervous system and neuroendocrine signaling.

Receptor Specificity and Mechanism

What makes TIP39 particularly intriguing to researchers is its high degree of selectivity. It is a neuropeptide and parathyroid hormone receptor type 2 (PTH2R) agonist that acts via its endogenous class B G-protein coupled receptor.

One of the most verifiable aspects of this peptide is its binding affinity. TIP39 is a high affinity, potent agonist at both the human and rat PTH2 receptors. Crucially, the literature confirms that TIP39 does not appreciably activate the PTH1 receptor, which highlights its utility in experiments where receptor-specific activation is desired. When it binds to the PTH2R, it triggers intracellular signaling pathways, including the activation of adenyl cyclase and the subse by RE Weaver · 2017 · Cited by 15 — TIP39 (“tuberoinfundibular peptide of 39 residues”) acts via the parathyroid hormone 2 receptor, PTH2, a Family B G protein-coupled receptor  quent elevation of intracellular calcium levels.

Experimental Applications and Research Tools

In laboratory settings, researchers often utilize synthetic versions of this molecule. Because TIP39 is an agonist for Parathyroid Hormone 2 Receptor, it is frequently used to study the tuberoinfundibular neuropeptide pathways.

For those looking to modulate these interactions, the tuberoinfundibular peptide (7-39), often abbreviated as TIP(7-39), serves as a significant antagonist. This specific variation—tuberoinfundibular peptide (7–39)—is often utilized in studies to observe the inhibition of the PTH2R, providing a balanced approach to understanding how TIP39 signaling modulates nociception.

Observations on Biological Activity

My interest in this peptide stems from the evolving data surrounding its role in the brain.

When sourcing these materials for research, it is essential to ensure that the Tip39 Peptide is of high purity. Because it is a peptide that activates human and rat PTH2 receptors, having a reliable, research-grade source is vital for consistent data collection. Whether you are investigating the TIP39 system or comparing it with other members of the PTH family, the specificity of this ligand remains its most valua The Neuroendocrine Functions of the Parathyroid ble attribute for scientific inquiry.
