A dynamic view of the endoplasmic reticulum: Scientist need to redraw picture of cell's biggest organelle. Super-resolution microscopy reveals surprising details of endoplasmic reticulum’s architecture
Increased spatiotemporal resolution reveals highly dynamic dense tubular matrices in the peripheral ER. Jonathon Nixon-Abell, Christopher J. Obara, Aubrey V. Weigel, Dong Li, Wesley R. Legant, C. Shan Xu, H. Amalia Pasolli, Kirsten Harvey, Harald F. Hess, Eric Betzig, Craig Blackstone and Jennifer Lippincott-Schwartz. Science. Published online October 27, 2016. doi: 10.1126/science.aaf3928.

The endoplasmic reticulum (ER) is a complex membranous structure that extends from the nuclear envelope to the cell periphery. It has important roles in many cellular processes, and numerous proteins are involved in maintaining its structure. Nixon-Abell et al. used superresolution approaches to look at the ER at the periphery of the cell, where the ER contacts many other cellular organelles (see the Perspective by Terasaki). This peripheral ER has been thought to comprise tubules and sheets; however, the higher-resolution view revealed that most of the “sheets” consist of a dense clustering of tubules. This dynamic meshwork may allow the ER to change its conformation rapidly in response to cellular needs.
