产品详情

  • 产品描述：
        ARG1，精氨酸酰化酶1（Arginase 1）是一种重要的代谢酶，它可以将精氨酸转化为尿素和 ornithine。ARG1的功能主要与尿素循环和氨基酸代谢有关。尿素循环是一种重要的生理过程，可以帮助人体排除过多的氨基酸代谢产物，将其转化为尿素，并排出体外。精氨酸酰化酶ARG1是尿素循环中的一个重要酶，它可以将精氨酸转化为尿素和 ornithine，起到调节氨基酸代谢的作用。
        研究发现，ARG1在多种疾病中的异常表达与疾病的发生和发展密切相关。例如，肝脏疾病、免疫系统疾病、神经系统疾病等都与ARG1的异常表达有关。因此，对ARG1的研究对于了解这些疾病的发生机制以及开发相应的治疗方法具有重要意义。

  • 最新研究进展：
        ARG1（Arginase 1）是一种酶，在肝脏、巨噬细胞、神经元等组织中广泛表达。ARG1主要参与氨基酸代谢和尿素循环，将精氨酸转化为尿素和天冬氨酸，调节血液中的氮代谢。最近研究表明，ARG1在调节免疫反应和肿瘤免疫逃逸中也起到重要作用。
     
  • 功能：
    Key element of the urea cycle converting L-arginine to urea and L-ornithine, which is further metabolized into metabolites proline and polyamides that drive collagen synthesis and bioenergetic pathways critical for cell proliferation, respectively; the urea cycle takes place primarily in the liver and, to a lesser extent, in the kidneys.; Functions in L-arginine homeostasis in nonhepatic tissues characterized by the competition between nitric oxide synthase (NOS) and arginase for the available intracellular substrate arginine. Arginine metabolism is a critical regulator of innate and adaptive immune responses. Involved in an antimicrobial effector pathway in polymorphonuclear granulocytes (PMN). Upon PMN cell death is liberated from the phagolysosome and depletes arginine in the microenvironment leading to suppressed T cell and natural killer (NK) cell proliferation and cytokine secretion. In group 2 innate lymphoid cells (ILC2s) promotes acute type 2 inflammation in the lung and is involved in optimal ILC2 proliferation but not survival. Plays a role in the immune response of alternatively activated or M2 macrophages in processes such as wound healing and tissue regeneration, immune defense against multicellular pathogens and parasites, and immune suppression and allergic inflammation; the regulatory outcome seems to be organ specific. In tumor-infiltrating dendritic cells (DCs) and myeloid-derived suppressor cells (MDSCs) plays a role in suppression of T cell-mediated antitumor immunity.
