The highly conserved retromer complex has been linked to cargo retrieval from endosomes to the trans-Golgi network. In this issue, Kvainickas et al. (2017. https://doi.org/10.1083/jcb.201702137) and Simonetti et al. (2017. https://doi.org/10.1083/jcb.201703015) fundamentally question the current retromer model and demonstrate that in mammalian cells, the individual retromer subcomplexes have functionally diverged to organize multiple distinct sorting pathways.
高度保守的逆行转运复合体(retromer complex)与从内体(endosomes)向反式高尔基网络(trans-Golgi network)回收货物有关。在本期中,Kvainickas 等人(2017. https://doi.org/10.1083/jcb.201702137)和 Simonetti 等人(2017. https://doi.org/10.1083/jcb.201703015)从根本上质疑了当前的逆行转运模型,并表明在哺乳动物细胞中,单个逆行转运亚复合物在功能上已经分化,以组织多种不同的分选途径。
