The peptide region containing residues 390-404 in ActivatedProtein C (APC) is essential for anticoagulant activity and is available for interaction with antibodies or with other proteins, such as the macromolecular substrates Factors Va or VIIIa. APC reg
Proinsulin C-peptide human acetate (Proinsulin C-peptide human acetate (33017-11-7 Free base)) 是一种由31个氨基酸残基组成的多肽,它连接胰岛素原的 A 链和 B 链以确保正确折叠,具有生物活性并调节细胞功能。
Protein Kinase C (19-31) TFA 是蛋白激酶 C (PKC)的抑制剂,是由 PKCa (残基 19-31) 伪底物调控域衍生而来,25 位丝氨酸取代野生型丙氨酸作为蛋白激酶 C 底物肽,用于检测蛋白激酶 C 的活性。Protein kinase C (PKC) TFA 通过磷酸化丝氨酸和苏氨酸氨基酸残基上的羟基来调控其它蛋白的功能。
Angiotensin II human (Angiotensin II) TFA 作为肾素/血管紧张素系统中关键的生物活性肽,扮演着血管收缩剂的角色并在调节人体血压中发挥中心作用。其主要通过与 G 蛋白偶联受体 (GPCRs)、血管紧张素 II 1型受体 (AT1R) 和血管紧张素 II 2型受体 (AT2R) 的相互作用来介导效应,包括刺激交感神经系统、增加醛固酮的生物合成和肾脏功能。此外,Angiotensin II humanTFA 促进血管平滑肌细胞的生长和 I 型及 III 型胶原在成纤维细胞中的合成,导致血管壁与心肌增厚及纤维化,并诱导细胞凋亡。还通过LOX-1依赖的氧化还原敏感路径诱导内皮细胞中的毛细血管形成。
Adrenomedullin (AM) (22-52), human [22-52-Adrenomedullin human], TFA, is a C-terminal truncated analogue of adrenomedullin and acts as an adrenomedullin receptor antagonist.
C-Reactive Protein (CRP) 77-82 is the 77-82 fragment of the annular (ring-shaped) C-Reactive Protein, the prototypic marker of inflammation, which serves as a cardiovascular risk marker and may promote atherogenesis.
Agouti-related peptide (AgRP) is a neuropeptide produced in the brain by the AgRP/NPY neuron. It is only synthesized in NPY containing cell bodies located in the ventromedial part of the arcuate nucleus in the hypothalamus. The appetite-stimulating effect
PACAP (1-38), a novel neuropeptide isolated from the bovine hypothalamus is more active than vasoactive intestinal peptide (VIP) in stimulating adenylate cyclase (EC50=7 nM). PACAP 1-38 (10-9 M) increased substance P (SP), gastrin releasing peptide (GRP),
β-CGRP,human tissue is one of the calcitonin peptide, through complex behavior of calcitonin receptor like receptor (CRLR) - and receptor activity - modifying proteins (increased), and 1 and 300 - nM CRLR IC50s/RAMP1 and CRLR/RAMP2 cells.
IRBP651-670(Interphotoreceptor retinoid-binding protein (651-670))是IRBP(亦称为retinoid-binding protein 3)的肽段,参与色素再生,通过将视黄醇和视黄醛从光感受细胞传输到视网膜色素上皮。在C57BL/6小鼠中,利用IRBP651-670诱导自身免疫性葡萄膜炎,这些小鼠携带H-2b单体型。用IRBP651-670(300 µg/动物)免疫增加了小鼠眼部IL-1β、IL-6、IL-17、TNF-α和IFN-γ水平,免疫细胞浸润及光感受器损伤。
