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.

A systematic screen for protein–lipid interactions in Saccharomyces cerevisiae

Molecular Systems Biology, 2010
Protein–metabolite networks are central to biological systems, but are incompletely understood. Here, we report a screen to catalog protein–lipid interactions in yeast.

Phosphatidylinositol 3-phosphate is generated in phagosomal membranes [PDF]

Current Biology, 2001
Phagocytic cells such as neutrophils and macrophages engulf and destroy invading microorganisms. After internalization, material captured within the phagosomal membrane is destroyed by a complex process of coordinated delivery of digestive enzymes and reactive oxygen species.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Phosphatidylinositol 3-Phosphate Recognition by the FYVE Domain [PDF]

Molecular Cell, 1999
Recognition of phosphatidylinositol 3-phosphate (Ptdlns(3)P) is crucial for a broad range of cellular signaling and membrane trafficking events regulated by phosphoinositide (PI) 3-kinases. PtdIns(3)P binding by the FYVE domain of human early endosome autoantigen 1 (EEA1), a protein implicated in endosome fusion, involves two beta hairpins and an alpha

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Dynamism of PI4-Phosphate during Interactions with Human Erythrocytes in Entamoeba histolytica

Microorganisms, 2020
Phosphatidylinositol phosphates (PIPs) are involved in many cellular events as important secondary messengers. In Entamoeba histolytica, a human intestinal protozoan parasite, virulence-associated mechanisms such as cell motility, vesicular traffic ...

Cyclic AMP concentrations modulate both calcium flux and hydrolysis of phosphatidylinositol phosphates in mouse T lymphocytes.

Journal of Immunology, 1988
Activation of T cells by lectins or mAb directed at components of the Ag-specific TCR results in hydrolysis of phosphorylated derivatives of phosphatidylinositol and an increase in intracellular free calcium concentration (Cai).

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Synaptojanin2 Mutation Causes Progressive High-frequency Hearing Loss in Mice

Frontiers in Cellular Neuroscience, 2020
Progressive hearing loss is very common in the human population but we know little about the underlying molecular mechanisms. Synaptojanin2 (Synj2) has been reported to be involved, as a mouse mutation led to a progressive increase in auditory thresholds
