  • 产品描述：
        LCN2 (Lipocalin-2), 又称NGAL (Neutrophil Gelatinase-Associated Lipocalin)，是一种由各种细胞产生的蛋白质，如肝细胞、肾小管上皮细胞、巨噬细胞和一些肿瘤细胞。LCN2可作为促炎性细胞因子，具有在免疫系统中发挥重要作用的抗菌和抗病毒活性。在肾脏损伤、心血管疾病和某些肿瘤中，LCN2的水平会显著升高，因此它也被用作这些疾病的生物标志物。

  • 最新研究进展：
    LCN2（鲸蓝蛋白2）是一种铁载体蛋白，广泛存在于哺乳动物的体液和细胞中。最近的研究表明，LCN2在多种疾病的发生发展中发挥重要作用，如肿瘤、心血管疾病、炎症性疾病等。此外，LCN2还可能参与多种生理过程，如细胞凋亡、铁代谢等。
  • 功能：
    Iron-trafficking protein involved in multiple processes such as apoptosis, innate immunity and renal development. Binds iron through association with 2,3-dihydroxybenzoic acid (2,3-DHBA), a siderophore that shares structural similarities with bacterial enterobactin, and delivers or removes iron from the cell, depending on the context. Iron-bound form (holo-24p3) is internalized following binding to the SLC22A17 (24p3R) receptor, leading to release of iron and subsequent increase of intracellular iron concentration. In contrast, association of the iron-free form (apo-24p3) with the SLC22A17 (24p3R) receptor is followed by association with an intracellular siderophore, iron chelation and iron transfer to the extracellular medium, thereby reducing intracellular iron concentration. Involved in apoptosis due to interleukin-3 (IL3) deprivation: iron-loaded form increases intracellular iron concentration without promoting apoptosis, while iron-free form decreases intracellular iron levels, inducing expression of the proapoptotic protein BCL2L11/BIM, resulting in apoptosis. Involved in innate immunity; limits bacterial proliferation by sequestering iron bound to microbial siderophores, such as enterobactin. Can also bind siderophores from M.tuberculosis.
