Folding-competent and folding-defective forms of Ricin A chain have different fates following retrotranslocation from the endoplasmic reticulum [PDF]

, 2010
We report that a toxic polypeptide retaining the potential to refold upon dislocation from the endoplasmic reticulum (ER) to the cytosol (ricin A chain; RTA) and a misfolded version that cannot (termed RTAΔ), follow ER-associated degradation (ERAD ...

Eeyarestatin 1 interferes with both retrograde and anterograde intracellular trafficking pathways [PDF]

, 2011
Background: The small molecule Eeyarestatin I (ESI) inhibits the endoplasmic reticulum (ER)-cytosol dislocation and subsequent degradation of ERAD (ER associated protein degradation) substrates.

Retrograde transport pathways utilised by viruses and protein toxins [PDF]

, 2006
A model has been presented for retrograde transport of certain toxins and viruses from the cell surface to the ER that suggests an obligatory interaction with a glycolipid receptor at the cell surface. Here we review studies on the ER trafficking cholera

Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...
