An unsolved mystery in cell biology is how unusually large secretory cargoes are exported from the endoplasmic reticulum. In this issue, Santos et al. (2016. J. Cell Biol http://dx.doi.org/10.1083/jcb.201603072) report the function of a Mia2/cTAGE5 transcript fusion, named TALI, in the endoplasmic reticulum export of chylomicrons and very low-density lipoproteins, but not collagen XII.
细胞生物学中一个未解之谜是异常大的分泌性货物如何从内质网输出。在本期中,桑托斯等人(2016年。《细胞生物学杂志》http://dx.doi.org/10.1083/jcb.201603072)报道了一种名为TALI的Mia2/cTAGE5转录融合体在乳糜微粒和极低密度脂蛋白的内质网输出中的功能,但在XII型胶原蛋白的内质网输出中不起作用。
