这个甘丙肽家族成员是从猪下丘脑中分离出来的。它是一种60个氨基酸的肽,与甘丙肽不同,它有一个非酰胺化的C末端。GALP氨基酸残基(9-21)与甘丙肽的生物活性N-末端(1-13)部分相同。受体结合研究表明,GALP对甘丙肽受体2具有高亲和力(GALR2;IC₅₀ = 0.24nM)和对GALR1受体的较低亲和力(IC₅₀ = 4.3nM)。因此,GALP是优先结合GALR2受体的内源性配体,而甘丙肽是相对非选择性的。
This member of the galanin family has been isolated from porcine hypothalamus. It is a 60 amino acid peptide that, unlike galanin, has a non-amidated C-terminus. GALP amino acid residues (9-21) are identical to the biologically active N-terminal (1-13) portion of galanin. Receptor binding studies revealed that GALP had a high affinity for the galanin receptor 2 (GALR2; IC₅₀ = 0.24 nM) and a lower affinity for the GALR1 receptor (IC₅₀ = 4.3 nM). GALP is therefore an endogenous ligand that preferentially binds the GALR2 receptor, whereas galanin is relatively non-selective.
甘丙肽样肽(猪)是从猪下丘脑中分离出来的一种与甘丙肽受体结合的神经肽。它是一种内源性配体,优先与GALR2受体结合,并在调节瘦素(一种饱腹激素)的作用中发挥作用。它是一种强效的血管活性肽,被认为与炎症反应有关。
Galanin-Like Peptide (porcine) is a GALR2 (galanin receptor)-binding neuropeptide isolated from porcine hypothalamus. It is an endogenous ligand that preferentially binds to GALR2 receptors and plays a role in regulating the effects of leptin, a satiety hormone. It is a potent vasoactive peptide and is thought to be involved in inflammatory responses.
