Quality control mechanisms of protein biogenesis : proteostasis dies hard

Bergmann, Timothy Jan ; Brambilla Pisoni, Giorgia ; Molinari, Maurizio

In: AIMS biophysics, 2016, vol. 3, no. 4, p. 456-478

The biosynthesis of proteins entails a complex series of chemical reactions that transform the information stored in the nucleic acid sequence into a polypeptide chain that needs to properly fold and reach its functional location in or outside the cell. It is of no surprise that errors might occur that alter the polypeptide sequence leading to a non-functional proteins or that impede delivery...

Endoplasmic reticulum turnover : ER-phagy and other flavors in selective and non-selective ER clearance

Fregno, Ilaria ; Molinari, Maurizio

In: F1000Research, 2018, vol. 7, p. 454

The endoplasmic reticulum (ER) is a highly dynamic organelle in eukaryotic cells. It is deputed to lipid and protein biosynthesis, calcium storage, and the detoxification of various exogenous and endogenous harmful compounds. ER activity and size must be adapted rapidly to environmental and developmental conditions or biosynthetic demand. This is achieved on induction of thoroughly studied...
