#Lipids are fatty #molecules that play critical roles in cell function, including membrane structure, energy storage and nutrient absorption. Most lipids are made in a cell #organelle called the #endoplasmic reticulum, but specific lipid types are shuttled around to different parts of the cell depending on their purpose.

The Many FACES of Lipid Research

A new technology will give unprecedented views of lipid movement inside cells

How #lipids in the membrane of the #endoplasmic reticulum of #plant cells interact with #proteins to organize the first step of protein transport has long been an unsolved mystery.

Old Puzzle around Protein Distribution in Plant Cells Solved

Researchers in Bochum have discovered a control mechanism that may also operate beyond plants.

#UVRAG cooperates with cargo receptors to assemble the ER-phagy site
Yixian Cui and colleagues show that an #autophagy regulator promotes degradation of specific regions of the #endoplasmic reticulum independently of its role in #PI3KC3 complex II

Researchers reveal endoplasmic reticulum–associated protein degradation and control of grain size in rice

In a study published in The Plant Cell, researchers led by Li Yunhai at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences described a role for the endoplasmic reticulum (ER)–associated protein degradation in the regulation of grain size in rice (Oryza sativa).
