Reticulons (RTNs) are a group of membrane proteins localized on the ER and known to regulate ER structure and functions. Several studies have suggested that RTNs are involved in different important cellular functions such as changes in calcium homeostasis, ER-stress-mediated cell death, and autophagy. RTNs have been demonstrated to exert a cancer specific proapoptotic function via the interaction or the modulation of specific proteins. Reticulons have also been implicated in different signaling pathways which are at the basis of the pathogenesis of several neurodegenerative diseases. In this paper we discuss the accumulating evidence identifying RTN-1C protein as a promising target in the treatment of different pathologies such as cancer or neurodegenerative disorders.
网织蛋白(RTNs)是一类定位于内质网的膜蛋白,已知其可调节内质网的结构和功能。多项研究表明,网织蛋白参与不同的重要细胞功能,如钙稳态变化、内质网应激介导的细胞死亡和自噬。已证实网织蛋白通过与特定蛋白质相互作用或调节特定蛋白质发挥癌症特异性促凋亡功能。网织蛋白还与多种信号通路有关,这些信号通路是几种神经退行性疾病发病机制的基础。在本文中,我们讨论了越来越多的证据,这些证据表明RTN-1C蛋白是治疗癌症或神经退行性疾病等不同病症的一个有前景的靶点。
