TLQP-21TFA是VGF衍生的具有内分泌和内分泌特性的肽，是一种强效的G蛋白偶联受体补体3a受体1(C3aR1)激动剂(EC50:小鼠TLQP-21=10.3μM；人TLQP-21=68.8μM)。TLQP-21TFA激活C3aR1，从而诱导细胞内Ca2+的增加。TLQP-21TFA可用于研究调节伤害感受和其他相关生理功能。
TLQP-21 TFA, a VGF-derived peptide endowed of endocrine and extraendocrine properties, is a potent G-protein-coupled receptor complement-3a receptor1 (C3aR1) agonist (EC50: mouse TLQP-21=10.3 μM; human TLQP-21=68.8μM). TLQP-21 TFA activates C3aR1 to induce an increase of intracellular Ca2+. TLQP-21 TFA is used for the research in regulation of nociception and other relevant physiologic functions[1][2].
TLQP-21 TFA is a peptide of 21 amino acids. At a dose of 3 μM TLQP-21 induces up to ~69% of the corresponding contraction promoted by acetylcholine[1][2].
