Golgi Glycosylation [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2011
Glycosylation is a very common modification of protein and lipid, and most glycosylation reactions occur in the Golgi. Although the transfer of initial sugar(s) to glycoproteins or glycolipids occurs in the ER or on the ER membrane, the subsequent addition of the many different sugars that make up a mature glycan is accomplished in the Golgi.

ZDHHC12 Palmitoylates HDAC8 to Promote the Progression of Hepatocellular Carcinoma Associated with a Diet High in Saturated Fatty Acids

open access: yesAdvanced Science, EarlyView.
This study identifies ZDHHC12 as a critical mediator of PA‐induced HCC progression. Mechanistically, PA upregulates ZDHHC12 expression through SMARCA4 activation, leading to HDAC8 palmitoylation at Cys244 which blocks HSC70‐mediated lysosomal degradation of HDAC8, thereby promoting HCC development. These findings provide novel mechanistic insights into

Loss of O-Linked Protein Glycosylation in Burkholderia cenocepacia Impairs Biofilm Formation and Siderophore Activity and Alters Transcriptional Regulators

open access: yesmSphere, 2019
O-linked protein glycosylation is a conserved feature of the Burkholderia genus. The addition of the trisaccharide β-Gal-(1,3)-α-GalNAc-(1,3)-β-GalNAc to membrane exported proteins in Burkholderia cenocepacia is required for bacterial fitness and ...

Quorum Sensing Inhibits Type III‐A CRISPR‐Cas System Activity Through Repressing Positive Regulators SarA and ArcR in Staphylococcus Aureus

open access: yesAdvanced Science, EarlyView.
This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.

Akkermansia muciniphila‐Derived N‐Acetylspermidine Modulates the Localization of Intestinal α1,2‐Fucosylated Proteins to Maintain Gut Homeostasis

open access: yesAdvanced Science, EarlyView.
This study demonstrates that Akkermansia muciniphila alleviates colitis by enhancing intestinal α1,2‐fucosylation through its metabolite N‐acetylspermidine. Mechanistically, N‐acetylspermidine‐induced PIM1 inhibition promotes HDAC2‐mediated reduction of chromatin accessibility at TP73, thereby upregulating C1GALT1C1 to boost α1,2‐fucosylation.

Biosynthesis, structure, and biological activities of envelope protein gp65 of murine coronavirus. [PDF]

open access: yes, 1989
We have previously shown that gp65 (E3) is a virion structural protein which varies widely in quantity among different strains of mouse hepatitis virus (MHV). In this study, the biosynthetic pathway and possible biological activities of this protein were

Aberrant glycosylation patterns as potential biomarkers for diagnosis and disease progression in bullous pemphigoid

open access: yesFrontiers in Immunology
ObjectivesBullous pemphigoid (BP) is a prototypical autoimmune disease characterized by the production of autoantibodies against hemidesmosomal proteins BP180 and BP230.
