产品活性:beta-Amyloid(1-42) Antibody (YA6439) 是一种小鼠来源、无偶联标记、抗 β-淀粉样蛋白 (1-42) 的 IgG2b 单克隆抗体。它可用于人背景下的 WB、IHC-P、IHC-F、IF-Tissue 实验。
研究背景:APP 作为细胞表面受体,在神经元表面执行与神经突生长、神经元粘附和轴突发生相关的生理功能。相邻细胞上的 APP 分子相互作用促进突触发生。通过蛋白质相互作用参与细胞迁移和转录调控,能够通过与 APBB1-KAT5 结合促进转录激活,并通过与 Numb 相互作用抑制 Notch 信号传导。偶联凋亡诱导途径(如 G(o) 和 JIP 介导的途径),抑制 G(o) alpha ATPase 活性(by similar)。作为 kinesin I 膜受体,介导 β-分泌酶和 presenilin 1 的轴突运输(by similar),并在轴突中向前突触运输货物中发挥作用。通过铜离子还原参与铜稳态/氧化应激。体外实验中,铜金属化的 APP 可直接诱导神经元死亡或通过 Cu2+ 介导的低密度脂蛋白氧化增强毒性。通过与细胞外基质成分(如肝素和胶原蛋白 I 及 IV)结合调节神经突生长。含 BPTI 结构域的剪接亚型具有蛋白酶抑制剂活性。诱导 AGER 依赖性途径,涉及 p38 MAPK 激活,导致淀粉样蛋白 β 肽内化并引发培养皮质神经元线粒体功能障碍。为 GPC1 提供 Cu2+ 离子,促进一氧化氮(NO)释放和后续 GPC1 上硫酸乙酰肝素链的降解。淀粉样蛋白 β 肽是亲脂性金属螯合剂,具有金属还原活性,可结合铜、锌和铁等过渡金属,在体外将 Cu2+ 和 Fe(3+) 分别还原为 Cu(+) 和 Fe2+。淀粉样蛋白 β 肽与脑脊液中的脂蛋白、载脂蛋白 E/J 及血浆中的 HDL 颗粒结合,抑制金属催化脂蛋白氧化。促进 tau 蛋白聚集和 TPK II 介导的磷酸化,与过表达的 HADH2 相互作用导致氧化应激和神经毒性。Appicans 促进神经细胞与细胞外基质的粘附,可能调节大脑中的神经突生长。γ-CTF 肽及 caspase 切割肽(如 C31)是神经元凋亡的强效增强剂。

亚细胞定位:Membrane; Single-pass type I membrane protein. Membrane, clathrin-coated pit. Note=Cell surface protein that rapidly becomes internalized via clathrin-coated pits. During maturation, the immature APP (N-glycosylated in the endoplasmic reticulum) moves to the Golgi complex where complete maturation occurs (O-glycosylated and sulfated). After alpha-secretase cleavage, soluble APP is released into the extracellular space and the C-terminal is internalized to endosomes and lysosomes. Some APP accumulates in secretory transport vesicles leaving the late Golgi compartment and returns to the cell surface. Gamma-CTF(59) peptide is located to both the cytoplasm and nuclei of neurons. It can be translocated to the nucleus through association with APBB1 (Fe65). Beta-APP42 associates with FRPL1 at the cell surface and the complex is then rapidly internalized. APP sorts to the basolateral surface in epithelial cells. During neuronal differentiation, the Thr-743 phosphorylated form is located mainly in growth cones, moderately in neurites and sparingly in the cell body. Casein kinase phosphorylation can occur either at the cell surface or within a post-Golgi compartment.
