The endoplasmic reticulum (ER) is the portion of the cell responsible for manufacturing and folding proteins. Proteins are ...

Cells have extensive sets of intracellular membranes, which together compose the endomembrane system. The endomembrane system was first discovered in the late 1800s when scientist Camillo Golgi ...

The peripheral endoplasmic reticulum (ER) forms a continuous, dynamic network of tubules that plays an important role in protein transport and quality control, cellular signaling, and stress response.

Thomas Ostwald and David MacLennan were characterizing proteins that bind to calcium in the sarcoplasmic reticulum — a specialized type of endoplasmic reticulum found in muscle cells.

By influencing calcium homeostasis, local protein synthesis and the endoplasmic reticulum, a small protein called Rab10 emerges as a crucial cytoplasmic regulator of neuropeptide secretion.
