Dynamic Protein Phosphorylation in Streptococcus pyogenes during Growth, Stationary Phase, and Starvation

open access: yesMicroorganisms
Phosphorylation of proteins at serine, threonine, and tyrosine residues plays an important role in physiological processes of bacteria, such as cell cycle, metabolism, virulence, dormancy, and stationary phase functions. Little is known about the targets

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

open access: yesAdvanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced

Macrophage RSAD2 Couples mtDNA Synthesis With a Self‐Amplifying Inflammatory Circuit to Orchestrate Tissue Repair

open access: yesAdvanced Science, EarlyView.
Macrophage RSAD2 dually regulates CMPK2—the rate‐limiting enzyme for mitochondrial DNA synthesis—by suppressing its ubiquitination and promoting its phosphorylation via Csnk2a2 recruitment. This amplifies mtDNA production, which simultaneously activates a cGAS‐STING‐IRF3‐RSAD2 feedforward loop and the NLRP3 inflammasome, driving a self‐sustaining ...

Characterization of the function of a novel protein tyrosine phophatase predicted by the genome sequence of Arabidopsis thaliana [PDF]

open access: yes, 2003
Covalent modification of proteins by reversible phosphorylation, catalysed by specific protein kinases and phosphatases, is an important mechanism for enzyme activity regulation in metabolism and signalling pathways.

pERK Detection Assays Using the Surefire AlphaScreen® Kit (TGR Biosciences and PerkinElmer)

open access: yesBio-Protocol, 2013
Extracellular signal-regulated kinase 1 and 2 (ERK1/2) are serine/threonine protein kinases that are phosphorylated on Thr202/Tyr204 (ERK1) and Thr185/Tyr187 (ERK2).

DIXDC1 Promotes Lymphatic Metastasis and Resistance to Cuproptosis in Bladder Cancer Through Mediating DLAT

open access: yesAdvanced Science, EarlyView.
DIXDC1 drives bladder cancer progression by binding and stabilizing DLAT. This axis enhances NEK7 and CCNE2 mRNA stability to promote proliferation and lymphatic metastasis, while limiting copper‐induced DLAT oligomerization to reduce cuproptosis sensitivity, identifying DIXDC1 as a potential target linking metastasis with cuproptosis resistance ...

Tau Aggregate Imaging and Transcriptomics of Alzheimer's Disease Brain at Different Stages of Disease

open access: yesAdvanced Science, EarlyView.
The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.

Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.
