Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Therapeutic strategies for anchored kinases and phosphatases: exploiting short linear motifs and intrinsic disorder

open access: yesFrontiers in Pharmacology, 2015
Phosphorylation events that occur in response to the second messenger cAMP are controlled spatially and temporally by protein kinase A (PKA) interacting with A-kinase anchoring proteins (AKAPs).

A synthetic inhibitor of the mitogen-activated protein kinase cascade.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1995
Treatment of cells with a variety of growth factors triggers a phosphorylation cascade that leads to activation of mitogen-activated protein kinases (MAPKs, also called extracellular signal-regulated kinases, or ERKs).

Single‐cell insights into the role of T cells in B‐cell malignancies

open access: yesFEBS Letters, EarlyView.
Single‐cell technologies have transformed our understanding of T cell–tumor cell interactions in B‐cell malignancies, revealing new T‐cell subsets, functional states, and immune evasion mechanisms. This Review synthesizes these findings, highlighting the roles of T cells in pathogenesis, progression, and therapy response, and underscoring their ...

Characterization of Protein Kinase A and Protein Kinase C Phosphorylation of the N-Methyl-D-aspartate Receptor NR1 Subunit Using Phosphorylation Site-specific Antibodies*

open access: yesJournal of Biological Chemistry, 1997
Modulation of N-methyl-D-aspartate receptors in the brain by protein phosphorylation may play a central role in the regulation of synaptic plasticity. To examine the phosphorylation of the NR1 subunit of N-methyl-D-aspartate receptors in situ, we have ...

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.

Recruitment of long-lasting and protein kinase A-dependent long-term potentiation in the CA1 region of hippocampus requires repeated tetanization.

open access: yesLearning & memory (Cold Spring Harbor, N.Y.), 1994
To study how the late phase of long-term potentiation (LTP) in hippocampus arises, we examined the resulting LTP for its time course and its dependence on protein synthesis and different second-messenger kinases by applying various conditioning tetani ...

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

open access: yesFEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

Specificity and spatial dynamics of protein kinase A signaling organized by A-kinase-anchoring proteins.

open access: yesJournal of Molecular Endocrinology, 2010
Protein phosphorylation is the most common post-translational modification observed in cell signaling and is controlled by the balance between protein kinase and phosphatase activities.

TRAF2 binds to TIFA via a novel motif and contributes to its autophagic degradation

open access: yesFEBS Letters, EarlyView.
TRAF family members couple receptor signalling complexes to downstream outputs, but how they interact with these complexes is not always clear. Here, we show that during ADP‐heptose signalling, TRAF2 binding to TIFA requires two short sequence motifs in the C‐terminal tail of TIFA, which are distinct from the TRAF6 binding motif.
