转运蛋白18 kDa（TSPO）是由TspO/PBR结构域组成的一种蛋白质，以前被称为外周苯二氮卓受体（PER）。TSPO的主要生化功能是转运血红素、卟啉、甾体和阴离子，在生物合成、细胞呼吸、细胞增殖和细胞凋亡等过程中发挥重要作用。近年来，TSPO的生物学功能在植物中被记录。拟南芥TSPO蛋白（AtTSPO）由一个无内含子基因座（At 2g 47770）编码。研究表明AtTSPO受非生物胁迫和植物胁迫激素脱落酸（阿坝）的诱导。本文就其表达模式、亚细胞定位、相互作用蛋白及其生物学功能进行综述。最后对AtTSPO的未来研究方向进行了展望。(C)2015 Elsevier B. V.版权所有。
Translocator protein 18 kDa (TSPO) contains a structural domain of TspO/PBR, which was previously named peripheral benzodiazepine receptor (PER). The main biochemical functions of TSPO were reported to be transporting heme, porphyrin, steroid and anion, by which TSPO plays very important roles in the processes of biosynthesis, cellular respiration, cell proliferation and apoptosis in animals. In recent years, the biological functions of TSPOs were documented in plants. TSPO protein in Arabidopsis (AtTSPO) is encoded by a single intronless locus (At2g47770). It has been shown that AtTSPO is induced by abiotic stresses and plant stress hormone abscisic acid (ABA). In this review, we summarize the expression pattern, sub-cellular localization, interacting proteins, and biological functions. In addition, we discuss the future directions of study on AtTSPO.
