An ABC transporter containing a forkhead-associated domain interacts with a serine-threonine protein kinase and is required for growth of Mycobacterium tuberculosis in mice [PDF]

, 2005
Forkhead-associated (FHA) domains are modular phosphopeptide recognition motifs with a striking preference for phosphothreonine-containing epitopes. FHA domains have been best characterized in eukaryotic signaling pathways but have been identified in six

Nigericin‐Triggered Phosphodynamics in Inflammasome Formation and Pyroptosis

PROTEOMICS, EarlyView.
ABSTRACT Innate immune signaling relies heavily on phosphorylation cascades to mount effective immune responses. Although traditional innate immune signaling cascades following TLR4 stimulation have been investigated through a temporally quantitative phosphoproteomic lens, far fewer studies have applied these methods to distinct signaling following the

Protein phosphatase 5 regulates titin phosphorylation and function at a sarcomere-associated mechanosensor complex in cardiomyocytes. [PDF]

, 2018
Serine/threonine protein phosphatase 5 (PP5) is ubiquitously expressed in eukaryotic cells; however, its function in cardiomyocytes is unknown. Under basal conditions, PP5 is autoinhibited, but enzymatic activity rises upon binding of specific factors ...

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

A coordinated phosphorylation cascade initiated by MSK1 directs RAR alpha recruitment to target gene promoters [PDF]

, 2008
The nuclear retinoic acid (RA) receptor alpha (RARα) is a transcriptional transregulator that controls the expression of specific gene subsets through binding at response elements and dynamic interactions with coregulators, which are coordinated by

The protein phosphatase 4 - PEA15 axis regulates the survival of breast cancer cells [PDF]

, 2016
BACKGROUND: The control of breast cell survival is of critical importance for preventing breast cancer initiation and progression. The activity of many proteins which regulate cell survival is controlled by reversible phosphorylation, so that the ...

An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no

Non‐Coding RNAs in Breast Cancer Radioresistance: Mechanisms, Functional Roles and Translational Potentials

Cell Proliferation, EarlyView.
Non‐coding RNAs (ncRNAs) regulate breast cancer radioresistance via cell cycle, DNA repair and tumour microenvironment pathways. Targeting ncRNAs (e.g., HOTAIR and miR‐155) with RNA‐based therapies (ASOs and CRISPR) shows promise but faces delivery challenges.

Insulin Action on Polyunsaturated Phosphatidic Acid Formation in Rat Brain: An “In Vitro” Model with Synaptic Endings from Cerebral Cortex and Hippocampus [PDF]

, 2009
The highly efficient formation of phosphatidic acid from exogenous 1-stearoyl-2-arachidonoyl-sn-glycerol (SAG) in rat brain synaptic nerve endings (synaptosomes) from cerebral cortex and hippocampus is reported.

Melatonin and the Dental Pulp: A Scoping Review

International Endodontic Journal, EarlyView.
ABSTRACT Background In general medicine, melatonin is known to enhance wound healing and promote stem cell differentiation. Its potential relevance in endodontics, however, remains underexplored. Objectives This scoping review aimed to systematically assess the available evidence on the effects of melatonin (a) on dental pulp tissue and (b) on human ...
