锥虫的生化特性是最近对线粒体钙摄取通道的分子鉴定的基础,线粒体钙单一转运体或称MCU。这一发现导致了该通道的许多调节因子的发现,它们与MCU形成了一个高分子量的复合体。其中一些调节子已经在锥体中被生物信息识别出来,锥体是第一个被描述为MCU必不可少的真核生物。在锥虫体中,MCU对于缓冲细胞内钙离子的变化和激活细胞的生物能量学是重要的。未来在锥虫体内这一途径上的工作有望进一步深入了解这些迷人的真核生物的生物学,以及发现新靶标的潜力。
The biochemical peculiarities of trypanosomes were fundamental for the recent molecular identification of the long-sought channel involved in mitochondrial Ca2+ uptake, the mitochondrial Ca2+ uniporter or MCU. This discovery led to the finding of numerous regulators of the channel, which form a high molecular weight complex with MCU. Some of these regulators have been bioinformatically identified in trypanosomes, which are the first eukaryotic organisms described for which MCU is essential. In trypanosomes MCU is important for buffering cytosolic Ca2+ changes and for activation of the bioenergetics of the cells. Future work on this pathway in trypanosomes promises further insight into the biology of these fascinating eukaryotes, as well as the potential for novel target discovery.
