Regulation of CK2 Activity by Phosphatidylinositol Phosphates [PDF]
Journal of Biological Chemistry, 2005 The process of clathrin-coated vesicle (CCV) formation/disassembly involves numerous proteins that act cooperatively. Phosphorylation is an important regulatory mechanism governing protein interactions in CCVs, and many of the core and accessory proteins of the CCV machinery are reversibly phosphorylated in vivo.

A targeted mass spectrometric analysis of phosphatidylinositol phosphate species
Journal of Lipid Research, 2005 The development of a new mass spectrometric lipid profiling methodology permits the identification of cellular phosphatidylinositol monophosphate/phosphatidylinositol bisphosphate/phosphatidylinositol trisphosphate (PIP/PIP2/PIP3) species that includes ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

VIPP1 rods engulf membranes containing phosphatidylinositol phosphates [PDF]
Scientific Reports, 2019 AbstractIn cyanobacteria and plants, VIPP1 plays crucial roles in the biogenesis and repair of thylakoid membrane protein complexes and in coping with chloroplast membrane stress. In chloroplasts, VIPP1 localizes in distinct patterns at or close to envelope and thylakoid membranes. In vitro, VIPP1 forms higher-order oligomers of >1 MDa that organize

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Class III PI3K regulates organismal glucose homeostasis by providing negative feedback on hepatic insulin signalling. [PDF]
, 2015 Defective hepatic insulin receptor (IR) signalling is a pathogenic manifestation of metabolic disorders including obesity and diabetes. The endo/lysosomal trafficking system may coordinate insulin action and nutrient homeostasis by endocytosis of IR and ...
