細胞內銅的四大分布途徑與關鍵調控機制（天門冬氨酸銅Copper Aspartate、抗壞血酸銅Copper Ascorbate）。發表時間：2024-10-26 19:11 在細胞中，銅有4 種分布途徑：（1）自由基清除途徑：Cu/Zn-超氧化物歧化酶將銅送至超氧化物歧化酶 SOD1上。（2）線粒體途徑：細胞色素 C氧化酶17 將銅轉移到細胞色素 C 氧化酶（cytochrome Coxidase，COX）上以產生 ATP。（3）分泌途徑：銅通過抗氧化蛋白 1（Antioxidant 1，Atox1）傳送至反式高爾基體網絡中的銅轉運蛋白質α鏈（ATP‐dependentcopper transporter 7A，ATP7A）和銅轉運蛋白質β鏈（ATP‐dependent copper transporter 7B，ATP7B）。（4）細胞核途徑：細胞核通過銅傳感器，調節 CTR1 表達以適應銅濃度的變化。

Four major distribution pathways of copper in cells and key regulatory mechanisms (copper aspartate, copper ascorbate).
In cells, copper has four distribution pathways: (1) Free radical scavenging pathway: Cu/Zn-superoxide dismutase transfers copper to superoxide dismutase SOD1. (2) Mitochondrial pathway: Cytochrome C oxidase 17 transfers copper to cytochrome C oxidase (COX) to produce ATP. (3) Secretory pathway: Copper is transferred to the copper transport protein α chain (ATP-dependent copper transporter 7A, ATP7A) and copper transport protein β chain (ATP-dependent copper transporter 7B, ATP7B) in the trans-Golgi network through antioxidant protein 1 (Atox1). (4) Nuclear pathway: The nucleus regulates CTR1 expression through copper sensors to adapt to changes in copper concentration.
