Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS 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

A-Kinase Anchoring Protein-Lbc: A Molecular Scaffold Involved in Cardiac Protection

open access: yesJournal of Cardiovascular Development and Disease, 2018
Heart failure is a lethal disease that can develop after myocardial infarction, hypertension, or anticancer therapy. In the damaged heart, loss of function is mainly due to cardiomyocyte death and associated cardiac remodeling and fibrosis.

Galpha 12 and Galpha 13 Are Phosphorylated during Platelet Activation [PDF]

open access: yes, 1996
The ubiquitously expressed G-proteins G12 and G13 whose function is currently not clear have been shown to be activated in platelet membranes through receptors that stimulate platelet aggregation. We used intact human platelets to determine whether alpha

Structural Mechanism for the Specific Assembly and Activation of the Extracellular Signal Regulated Kinase 5 (ERK5) Module [PDF]

open access: yes, 2013
Mitogen-activated protein kinase (MAPK) activation depends on a linear binding motif found in all MAPK kinases (MKK). In addition, the PB1 (Phox and Bem1) domain of MKK5 is required for extracellular signal regulated kinase 5 (ERK5) activation.

Protein Kinase A Anchoring [PDF]

open access: yesJournal of Biological Chemistry, 1997
Specificity is perhaps the most enigmatic property of hormonemediated signaling pathways, especially when one considers that more than 30 hormones employ the ubiquitous second messengers, Ca, phospholipid, or cAMP, to relay messages from the cell membrane to intracellular effectors.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS 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.

Crystal Structures Reveal Hidden Domain Mechanics in Protein Kinase A (PKA)

open access: yesBiology, 2023
Cyclic-AMP-dependent protein kinase A (PKA) is a critical enzyme involved in various signaling pathways that plays a crucial role in regulating cellular processes including metabolism, gene transcription, cell proliferation, and differentiation.

Fyn-Mediated Regulation of Protein Kinase A [PDF]

open access: yes, 2017
Protein kinases are enzymes important for signal transduction in the regulation of cellular processes. The cAMP-dependent protein kinase A (PKA) has been previously reported to regulate the activity of the Src family kinase Fyn, an event important for ...

Plasma membrane association by N-acylation governs PKG function in Toxoplasma gondii [PDF]

open access: yes, 2017
Cyclic GMP (cGMP)-dependent protein kinase (protein kinase G [PKG]) is essential for microneme secretion, motility, invasion, and egress in apicomplexan parasites, However, the separate roles of two isoforms of the kinase that are expressed by some ...

Autophosphorylation at serine 166 regulates RIP kinase 1-mediated cell death and inflammation [PDF]

open access: yes, 2020
Receptor interacting protein kinase 1 (RIPK1) regulates cell death and inflammatory responses downstream of TNFR1 and other receptors, and has been implicated in the pathogenesis of inflammatory and degenerative diseases.
