Glycosylation-directed quality control of protein folding

C Xu, DTW Ng - Nature reviews Molecular cell biology, 2015 - nature.com
Membrane-bound and soluble proteins of the secretory pathway are commonly glycosylated
in the endoplasmic reticulum. These adducts have many biological functions, including …

The function of heat-shock proteins in stress tolerance: degradation and reactivation of damaged proteins

DA Parsell, S Lindquist - Annual review of genetics, 1993 - go.gale.com
Complex processes are involved in the protection of cells and organisms by heat shock
proteins (hsps). Aberrant protein production due to high temperatures is prevented by the …

Intracellular functions of N-linked glycans

A Helenius, M Aebi - Science, 2001 - science.org
N-linked oligosaccharides arise when blocks of 14 sugars are added cotranslationally to
newly synthesized polypeptides in the endoplasmic reticulum (ER). These glycans are then …

Calnexin cycle–structural features of the ER chaperone system

G Kozlov, K Gehring - The FEBS journal, 2020 - Wiley Online Library
The endoplasmic reticulum (ER) is the major folding compartment for secreted and
membrane proteins and is the site of a specific chaperone system, the calnexin cycle, for …

Roles of N-linked glycans in the endoplasmic reticulum

A Helenius, M Aebi - Annual review of biochemistry, 2004 - annualreviews.org
▪ Abstract From a process involved in cell wall synthesis in archaea and some bacteria, N-
linked glycosylation has evolved into the most common covalent protein modification in …

Quality control in the endoplasmic reticulum

L Ellgaard, A Helenius - Nature reviews Molecular cell biology, 2003 - nature.com
The endoplasmic reticulum (ER) has a quality-control system for'proof-reading'newly
synthesized proteins, so that only native conformers reach their final destinations. Non …

Rescue of α-synuclein aggregation in Parkinson's patient neurons by synergistic enhancement of ER proteostasis and protein trafficking

I Stojkovska, WY Wani, F Zunke, NR Belur… - Neuron, 2022 - cell.com
Neurodegenerative disorders are characterized by a collapse in proteostasis, as shown by
the accumulation of insoluble protein aggregates in the brain. Proteostasis involves a …

The delicate balance between secreted protein folding and endoplasmic reticulum-associated degradation in human physiology

CJ Guerriero, JL Brodsky - Physiological reviews, 2012 - journals.physiology.org
Protein folding is a complex, error-prone process that often results in an irreparable protein
by-product. These by-products can be recognized by cellular quality control machineries …

Chaperone-mediated protein folding

AL Fink - Physiological reviews, 1999 - journals.physiology.org
The folding of most newly synthesized proteins in the cell requires the interaction of a variety
of protein cofactors known as molecular chaperones. These molecules recognize and bind …

Role of N-linked oligosaccharide recognition, glucose trimming, and calnexin in glycoprotein folding and quality control.

C Hammond, I Braakman… - Proceedings of the …, 1994 - National Acad Sciences
Using a pulse-chase approach combined with immunoprecipitation, we showed that newly
synthesized influenza virus hemagglutinin (HA) and vesicular stomatitis virus G protein …
