Chemical Synthesis of Glycosylphosphatidylinositol Anchors [PDF]

, 2012
Many eukaryotic cell-surface proteins and glycoproteins are anchored to the plasma membrane by glycosylphosphatidylinositols (GPIs), a family of glycolipids that are post-translationally attached to proteins at their C-termini. GPIs and GPI-anchored proteins play important roles in many biological and pathological events, such as cell recognition and ...

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

CD177 Deficiency Defines a Stable Subtype of Human Neutrophil Granulocytes with Tumor Promoting Activity

Advanced Science, EarlyView.
Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

Programmable Nanobody‐Targeting Chimeras Enable Intracellular Viral Protein Degradation

Advanced Science, EarlyView.
Nab‐TAC enables targeted degradation of HBV surface antigen (HBsAg) in vivo. By fusing nanobody‐based recognition domains with programmable proteasome‐recruiting degradation signals, Nab‐TAC reduces HBsAg levels in a hydrodynamic HBV mouse model. ABSTRACT Chronic hepatitis B virus (HBV) infection remains a major global health challenge, largely because

N-acetylglucosamine supplementation fails to bypass the critical acetylation of glucosamine-6-phosphate required for Toxoplasma gondii replication and invasion.

PLoS Pathogens
The cell surface of Toxoplasma gondii is rich in glycoconjugates which hold diverse and vital functions in the lytic cycle of this obligate intracellular parasite.

Biosynthesis and deficiencies of glycosylphosphatidylinositol

Proceedings of the Japan Academy, Series B, 2014
At least 150 different human proteins are anchored to the outer leaflet of the plasma membrane via glycosylphosphatidylinositol (GPI). GPI preassembled in the endoplasmic reticulum is attached to the protein's carboxyl-terminus as a post-translational modification by GPI transamidase. Twenty-two PIG (for Phosphatidyl Inositol Glycan) genes are involved

The GPI sidechain of Toxoplasma gondii inhibits parasite pathogenesis

mBio
Glycosylphosphatidylinositols (GPIs) are highly conserved anchors for eukaryotic cell surface proteins. The apicomplexan parasite, Toxoplasma gondii, is a widespread intracellular parasite of warm-blooded animals whose plasma membrane is covered with GPI-

Using Synthetic Glycans to Investigate Anti‐Glycan Antibodies and Explore Their Medical Potential

Angewandte Chemie International Edition, EarlyView.
Anti‐glycan antibodies are essential in health and disease. Access to novel glycan structures paves the way for progress in antibody profiling for biomarker discovery, antibody development, and vaccine design. We summarize the strategies to synthesize and utilize synthetic glycans for the development and application of anti‐glycan antibodies in basic ...

Differential sensitivity to SHH signaling and neural crest‐mediated Gas1 expression regulate jaw size during development and evolution

Developmental Dynamics, EarlyView.
Abstract Background Developmental control of jaw size is crucial to prevent birth defects and facilitate evolutionary adaptation. We have shown that jaw size is established by neural crest mesenchyme (NCM), which are progenitor cells that migrate into the mandibular primordia and produce the jaws.
