Tuberoinfundibular 肽 TIP-39 最初从牛下丘脑中分离,被发现是 pTH2 受体的有效选择性激动剂,可调节垂体激素分泌和参与疼痛感知的脊髓区域。合成的 TIP-39 激活人和大鼠 pTH2 受体,EC 50 分别为 0.5 ± 0.12 nM 和 0.8 ± 0.3 nM。在大鼠 pTH2 受体上,TIP-39 比 pTH (EC₅₀ = 49 ± 23 nM) 更有效。TIP-39的发现为研究神经系统内外的pTH2受体功能提供了重要工具。

Tuberoinfundibular peptide, TIP-39, originally isolated from bovine hypothalamus was found to be a potent and selective agonist of the pTH2 receptor which regulates pituitary hormone secretion and spinal cord regions involved in pain perception. Synthetic TIP-39 activated the human and rat pTH2 receptors with EC₅₀ of 0.5 ± 0.12 nM and 0.8 ± 0.3 nM, respectively. TIP-39 was much more potent than pTH (EC₅₀ = 49 ± 23 nM) at the rat pTH2 receptor. The discovery of TIP-39 provides an important tool for the investigation of the pTH2 receptor functions inside and outside the nervous system.
