Stay in touch with the endoplasmic reticulum
Science China Life SciencesThe endoplasmic reticulum (ER), which is composed of a continuous network of tubules and sheets, forms the most widely distributed membrane system in eukaryotic cells. As a result, it engages a variety of organelles by establishing membrane contact sites (MCSs). These contacts regulate organelle positioning and remodeling, including fusion and fission,

Compartmentation of the rough endoplasmic reticulum
Molecular and Cellular Biochemistry, 1986It has become evident during recent years that a wide variety of proteins are synthesized on membrane-bound polysomes, very many of which are not ultimately secreted from the cell. The majority of proteins appear to go through some form of post-translational modification before the final appearance of an 'active' product, and in some cases the ...

ENDOPLASMIC RETICULUM–ASSOCIATED DEGRADATION
Annual Review of Cell and Developmental Biology, 2005Secretory and transmembrane proteins enter the secretory pathway through the protein-conducting Sec61 channel in the membrane of the endoplasmic reticulum. In the endoplasmic reticulum, proteins fold, are frequently covalently modified, and oligomerize before they are packaged into transport vesicles that shuttle them to the Golgi complex.

Endoplasmic reticulum in viral infection
2020Virus exploits host cellular machinery to replicate and form new viral progeny and endoplasmic reticulum (ER) plays central role in the interplay between virus and host cell. Here I will discuss how cellular functions of ER being utilized by viruses from different families during different stages of pathogenesis.

Selenoproteins in the Endoplasmic Reticulum [PDF]
, 2011 The endoplasmic reticulum (ER) is an organelle which is present in all eukaryotic cells. The ER is a major compartment where protein folding, glycosylation, and disulfide bond formation occur. Selenocysteine containing proteins (selenoproteins) are a subgroup of thiol oxidoreductases. Recent studies demonstrated that 7 of 25 known human selenoproteins,

Biology of the Endoplasmic Reticulum
2012Since its discovery in 1945, our knowledge of the structure and many functions of the endoplasmic reticulum (ER) has advanced at a phenomenal rate. Early studies focused on the structure, which was then followed by biochemical and functional studies associated with calcium storage and release from the ER, protein folding and secretion, ER associated ...

1973
In 1945 Porter et al. discovered a fine network in the endoplasm of chicken fibroblasts which was called endoplasmic reticulum and abbreviated ER (Porter 1948). In thin sections it appears as profiles of isolated strands, elongated vesicles and cisternae, but serial sections, electron stereographs and freeze etchings (Frey-Wyssling and Muhlethaler 1965,
