Defining albumin as a glycoprotein with multiple N-linked glycosylation sites

Journal of Translational Medicine
Background Glycosylation is an enzyme-catalyzed post-translational modification that is distinct from glycation and is present on a majority of plasma proteins.

Beyond the Sequon: Sites of N-Glycosylation [PDF]

, 2012
Asparagine (N-) linked protein glycosylation is a common and essential post-translational modification of proteins in eukaryotes, archaea and some bacteria. It plays crucial roles in protein folding and in regulation of protein function. Although the general principles of Nglycosylation have been long known, the precise details governing whether a ...

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

N-glycosylation regulates photosynthetic efficiency of Arabidopsis thaliana

Photosynthetica, 2020
N-glycosylation is one of the most important protein modifications in eukaryotes. It has been well established that N-glycosylation plays multiple roles in regulating stress tolerance of plants.

Congenital Disorders of N-Glycosylation Including Diseases Associated With O- as Well as N-Glycosylation Defects [PDF]

Pediatric Research, 2006
The congenital disorders of N-glycosylation (CDG), a steadily increasing group of multi-systemic disorders, have severe clinical implications in infancy and early childhood. The various inborn errors responsible adversely affect N-glycosylation of lysosomal proteins because of either failing assembly of lipid-linked (LL) oligosaccharides (OS) in the ...

Radiation‐Induced Tumor‐Intrinsic LTβR N‐Glycosylation Suppresses Pyroptosis Through TRIM28‐Mediated PCBP2 SUMOylation to Promote Gastric Cancer Radioresistance

Advanced Science, EarlyView.
Radiotherapy triggers LTβR N‐glycosylation, enhancing its overall protein stability and nuclear retention. This accumulation drives TRIM28‐mediated PCBP2 SUMOylation, suppressing pyroptosis and conferring gastric cancer radioresistance. Therapeutically, a targeted nanoplatform (cRGD‐Lipo@EMD) effectively disrupts this regulatory axis, offering a highly

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

A Chemically Defined Four‐Component Self‐Adjuvanting Tn Vaccine Activating Mincle, FcγR, and CD206 for Enhanced Antitumor Immunity

Advanced Science, EarlyView.
A fully synthetic four‐component vaccine has been developed combining Tn antigen, vizantin (Mincle agonist), rhamnose (antibody recruitment), and mannose (CD206 targeting). By synergistically activating Mincle, FcγR, and CD206 pathways, it elicits strong IgG switching and cytotoxic T‐cells, significantly inhibiting tumors in mice.

Raider of the lost N-glycans – Localizing rare and frequently overlooked IgG N-glycans with sulfation or bisecting LacNAc

Frontiers in Molecular Biosciences
Immunoglobulin G (IgG) is the most abundant immunoglobulin in human blood. Here it plays a central role in the immune system by recognizing antigens and mediating effector functions of the humoral immune defense.

p53 gain-of-function mutations promote metastasis via ENTPD5 upregulation and enhanced N-glycoprotein folding

Molecular & Cellular Oncology, 2017
Mutations in cancer abolish normal tumor suppressive functions of tumor protein p53 (TP53, best known as p53) and convert it into an oncogene. We recently reported the identification of ectonucleoside triphosphate diphosphohydrolase 5 (ENTPD5) as a ...
