TFRC 蛋白, Human (HEK293, His)

TFRC protein promotes cellular iron uptake through receptor-mediated endocytosis. TFRC is essential for erythroid and nervous system development and plays a crucial role in iron homeostasis. TFRC Protein, Human (HEK293, His) is the recombinant human-derived TFRC protein, expressed by HEK293 , with N-6*His labeled tag. The total length of TFRC Protein, Human (HEK293, His) is 660 a.a., with molecular weight of 78-90 kDa.

研究表明，TFRC 蛋白通过受体介导的配体转铁蛋白受体内吞作用进入专门的内体，从而促进细胞铁的吸收。该过程涉及内体酸化，导致铁释放，然后将脱铁转铁蛋白-受体复合物再循环到细胞表面，同时pH值恢复至中性，随后脱铁转铁蛋白与其受体的亲和力丧失。TFRC 对红细胞和神经系统发育至关重要，是铁稳态的重要参与者。遗传性血色素沉着症蛋白 HFE 与转铁蛋白竞争在重叠 C 末端位点的结合。TFRC 通过铁摄取积极调节 T 细胞和 B 细胞增殖，并充当脂质传感器，通过调节 JNK 通路调节线粒体融合。根据膳食硬脂酸盐水平，当硬脂酸盐含量低时，TFRC 会促进 JNK 通路激活和线粒体融合蛋白 MFN2 降解；当硬脂酸盐含量高时，TFRC 会抑制 JNK 通路激活和 MFN2 降解。此外，在微生物感染过程中，TFRC 充当新世界沙粒病毒的受体，包括瓜纳里托病毒、胡宁病毒和马丘波病毒。
