KDEL Receptors Assist Dengue Virus Exit from the Endoplasmic Reticulum.
Membrane receptors at the surface of target cells are key host factors for virion entry; however, it is unknown whether trafficking and secretion of progeny virus requires host intracellular receptors. In this study, we demonstrate that dengue virus (DENV) interacts with KDEL receptors (KDELR), which cycle between the ER and Golgi apparatus, for vesicular transport from ER to Golgi. Depletion o...
متن کاملLigand-binding domain determines endoplasmic reticulum exit of AMPA receptors.
AMPA receptors (AMPARs) are tetrameric ion channels that mediate rapid glutamate signaling in neurons and many non-neuronal cell types. Endoplasmic reticulum (ER) quality control mechanisms permit only correctly folded functional receptors to be delivered to the cell surface. We analyzed the biosynthetic maturation and transport of all 12 GluA1-4 subunit splice variants as homomeric receptors a...
متن کاملProtein Sorting upon Exit from the Endoplasmic Reticulum
It is currently thought that all secretory proteins travel together to the Golgi apparatus where they are sorted to different destinations. However, the specific requirements for transport of GPI-anchored proteins from the endoplasmic reticulum to the Golgi apparatus in yeast could be explained if protein sorting occurs earlier in the pathway. Using an in vitro assay that reconstitutes a single...
متن کاملCutting edge: Tapasin is retained in the endoplasmic reticulum by dynamic clustering and exclusion from endoplasmic reticulum exit sites.
Tapasin retains empty or suboptimally loaded MHC class I molecules in the endoplasmic reticulum (ER). However, the molecular mechanism of this process and how tapasin itself is retained in the ER are unknown. These questions were addressed by tagging tapasin with the cyan fluorescent protein or yellow fluorescent protein (YFP) and probing the distribution and mobility of the tagged proteins. YF...
متن کاملEndoplasmic reticulum stress regulates inflammation in adipocyte of obese rats via toll-like receptors 4 signaling
Objective(s): To explore whether endoplasmic reticulum (ER) stress regulates inflammation in adipose tissue of obese rats via TLR4 signaling. Materials and Methods: Sprague Dawley rats were randomly divided into four groups, and body weight, food intake, and free fatty acids (FFA) were measured. Real-time PCR and Western blot were used to determine mRNA or protein expression of TLR4, TRAF6, IKK...
