Negative regulation of urokinase receptor activity by a GPI-specific phospholipase C in breast cancer cells

eLife, 2017
The urokinase receptor (uPAR) is a glycosylphosphatidylinositol (GPI)-anchored protein that promotes tissue remodeling, tumor cell adhesion, migration and invasion.

Probing Enzymes Late in the Trypanosomal Glycosylphosphatidylinositol Biosynthetic Pathway with Synthetic Glycosylphosphatidylinositol Analogues [PDF]

ACS Chemical Biology, 2008
Glycosylphosphatidylinositol (GPI)-anchored proteins are abundant in the protozoan parasite Trypanosoma brucei, the causative agent of African sleeping sickness in humans and the related disease Nagana in cattle, and disruption of GPI biosynthesis is genetically and chemically validated as a drug target.

Defective lipid remodeling of GPI anchors in peroxisomal disorders, Zellweger syndrome, and rhizomelic chondrodysplasia punctata

Journal of Lipid Research, 2012
Many cell surface proteins in mammalian cells are anchored to the plasma membrane via glycosylphosphatidylinositol (GPI). The predominant form of mammalian GPI contains 1-alkyl-2-acyl phosphatidylinositol (PI), which is generated by lipid remodeling from

Semisynthesis of Functional Glycosylphosphatidylinositol‐Anchored Proteins [PDF]

Angewandte Chemie, 2020
AbstractGlypiation is a common posttranslational modification of eukaryotic proteins involving the attachment of a glycosylphosphatidylinositol (GPI) glycolipid. GPIs contain a conserved phosphoglycan that is modified in a cell‐ and tissue‐specific manner.

Glycosylphosphatidylinositol Anchors from Galactomannan and GPI-Anchored Protein Are Synthesized by Distinct Pathways in Aspergillus fumigatus

Journal of Fungi, 2018
Glycosylphosphatidylinositols (GPIs) are lipid anchors allowing the exposure of proteins at the outer layer of the plasma membrane. In fungi, a number of GPI-anchored proteins (GPI-APs) are involved in the remodeling of the cell wall polymers.

Glycosylphosphatidylinositol biosynthesis and remodeling are required for neural tube closure, heart development, and cranial neural crest cell survival

eLife, 2019
Glycosylphosphatidylinositol (GPI) anchors attach nearly 150 proteins to the cell membrane. Patients with pathogenic variants in GPI biosynthesis genes develop diverse phenotypes including seizures, dysmorphic facial features and cleft palate through an ...

Bioorthogonal Tools for Ethanolamine Lipids and Protein Conjugates

Angewandte Chemie, EarlyView.
An alkyne‐tagged ethanolamine analog (AlkEA) enables bioorthogonal, metabolic labeling of endogenous phosphatidylethanolamine (PE) and its protein modifications. AlkEA is incorporated into PE via the Kennedy pathway, allowing CuAAC‐based visualization of PE and affinity capture of PE‐conjugated LC3, ubiquitin, and GPI‐anchored proteins.

The small population of PIG-A mutant cells in myelodysplastic syndromes do not arise from multipotent hematopoietic stem cells

Haematologica, 2012
Background Patients with paroxysmal nocturnal hemoglobinuria harbor clonal glycosylphosphatidylinositol-anchor deficient cells arising from a multipotent hematopoietic stem cell acquiring a PIG-A mutation.

GPIHBP1, a GPI-anchored protein required for the lipolytic processing of triglyceride-rich lipoproteins

Journal of Lipid Research, 2009
GPIHBP1, a small glycosylphosphatidylinositol-anchored glycoprotein, is required for the lipolytic processing of triglyceride-rich lipoproteins. GPIHBP1 knockout mice exhibit chylomicronemia, even on a low-fat diet, with plasma triglyceride levels of 3 ...
