Uterine Endoplasmic Reticulum Stress and Its Unfolded Protein Response May Regulate Caspase 3 Activation in the Pregnant Mouse Uterus [PDF]
, 2013 We have previously proposed that uterine caspase-3 may modulate uterine contractility in a gestationally regulated fashion. The objective of this study was to determine the mechanism by which uterine caspase-3 is activated and consequently controlled in ...

Degradation of a Cytosolic Protein Requires Endoplasmic Reticulum-associated Degradation Machinery [PDF]
Journal of Biological Chemistry, 2008 Protein misfolding is monitored by a variety of cellular "quality control" systems. Endoplasmic reticulum (ER) quality control handles misfolded secretory and membrane proteins and is well characterized. However, less is known about the quality control of misfolded cytosolic proteins (CytoQC).

The proteasome cap RPT5/Rpt5p subunit prevents aggregation of unfolded ricin A chain [PDF]
, 2013 The plant cytotoxin ricin enters mammalian cells by receptor-mediated endocytosis, undergoing retrograde transport to the endoplasmic reticulum (ER) where its catalytic A chain (RTA) is reductively separated from the holotoxin to enter the cytosol and ...

Dynamic insertion of membrane proteins at the endoplasmic reticulum [PDF]
, 2005 Most eukaryotic membrane proteins are cotranslationally integrated into the endoplasmic reticulum membrane by the Sec61 translocation complex. They are targeted to the translocon by hydrophobic signal sequences which induce the translocation of either ...

Discerning protein pools by selective staining with self‐labeling tags
FEBS Letters, EarlyView.Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Septin-dependent compartmentalization of the endoplasmic reticulum during yeast polarized growth [PDF]
, 2005 Polarized cells frequently use diffusion barriers to separate plasma membrane domains. It is unknown whether diffusion barriers also compartmentalize intracellular organelles.

The AAA-ATPase p97 facilitates degradation of apolipoprotein B by the ubiquitin-proteasome pathways⃞
Journal of Lipid Research, 2008 The ATPase associated with various cellular activities (AAA-ATPase) p97 (p97) has been implicated in the retrotranslocation of target proteins for delivery to the cytosolic proteasome during endoplasmic reticulum-associated degradation (ERAD ...

The microbiome in human skin aging
FEBS Letters, EarlyView.Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Destroy and exploit: catalyzed removal of hydroperoxides from the endoplasmic reticulum [PDF]
, 2013 Peroxidases are enzymes that reduce hydroperoxide substrates. In many cases, hydroperoxide reduction is coupled to the formation of a disulfide bond, which is transferred onto specific acceptor molecules, the so-called reducing substrates.
