Amino-terminal cysteine residues of RGS16 are required for palmitoylation and modulation of G(i)- and G(q)-mediated signaling [PDF]

open access: yes, 1999
RGS proteins (Regulators of G protein Signaling) are a recently discovered family of proteins that accelerate the GTPase activity of heterotrimeric G protein α subunits of the i, q, and 12 classes.

cGAS Inhibits ALDH2 to Suppress Lipid Droplet Function and Regulate MASLD Progression

open access: yesAdvanced Science, EarlyView.
cGAS is a cytosolic DNA sensor known for innate immune defense. cGAS binds and suppresses ALDH2 are showed, limiting acetyl‐CoA production. cGAS loss activates ALDH2, promoting histone acetylation, lipogenesis, and lipid droplets accumulation. cGas‐/‐ mice on a high‐fat diet show signs of worsened MASLD.

RGS10 shapes the hemostatic response to injury through its differential effects on intracellular signaling by platelet agonists. [PDF]

open access: yes, 2018
Platelets express ≥2 members of the regulators of G protein signaling (RGS) family. Here, we have focused on the most abundant, RGS10, examining its impact on the hemostatic response in vivo and the mechanisms involved.

LncRNA THUMPD3‐AS1 Regulates Behavioral and Synaptic Structural Abnormalities in Schizophrenia via miR‐485‐5p and ARHGAP8

open access: yesAdvanced Science, EarlyView.
Schizophrenia (SCZ) is linked to synaptic structural deficits driven by dysregulated noncoding RNAs. Using the novel ceRNAxis pipeline, THUMPD3‐AS1/miR‐485‐5p/ARHGAP8 is identified as a key regulator of actin cytoskeletal remodeling through noncanonical RhoB/C‐ROCK2 signaling. Modulating this axis ameliorates SCZ‐like phenotypes in mice and aligns with

ARL3 Enhances ERα Stability via USP10 Deubiquitination to Promote Endocrine Resistance and Drive Mitochondrial Metabolic Reprogramming in HR+ Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies ADP‐ribosylation factor‐like protein 3 (ARL3) as a novel chaperone that stabilizes estrogen receptor α (ERα) in breast cancer. ARL3 promotes tumor growth by recruiting USP10 to remove ubiquitin chains from ERα, preventing its degradation.

Expression of MHC II genes

open access: yes, 2005
Innate and adaptive immunity are connected via antigen processing and presentation (APP), which results in the presentation of antigenic peptides to T cells in the complex with the major histocompatibility (MHC) determinants.

HL-1 cells express an inwardly rectifying K+ current activated via muscarinic receptors comparable to that in mouse atrial myocytes [PDF]

open access: yes, 2010
An inwardly rectifying K^+ current is present in atrial cardiac myocytes that is activated by acetylcholine (I_{KACh}). Physiologically, activation of the current in the SA node is important in slowing the heart rate with increased parasympathetic tone ...

The importance of the GTP‐binding protein tissue transglutaminase in the regulation of cell cycle progression

open access: yesFEBS Letters, 1995
Tissue transglutaminase (tTgase) is a GTP‐binding Ca2+‐dependent enzyme which catalyses the post‐translational modification of proteins via ϵ(γ‐glutamyl) lysine bridges. Recent evidence suggests that the GTP‐binding activity of tTgase may be important in intracellular signalling thus explaining some of the diverse suggested roles for the enzyme. In the

Lactate Metabolic Reprogramming Mediated by CircRNA–LDHA Complex Facilitates Innate Immune Evasion of Liver Cancer

open access: yesAdvanced Science, EarlyView.
CircSMPD4 physically combines with lactate dehydrogenase A (LDHA) and reduces its acetylation level via SIRT2‐dependent deacetylation, thereby inhibiting chaperone‐mediated autophagy‐lysosome degradation of LDHA. Upregulating LDHA leads to increasing lactate production and extracellular export, which in turn suppresses natural killer cell cytotoxicity ...

The GAPs, GEFs, and GDIs of heterotrimeric G-protein alpha subunits

open access: yesInternational Journal of Biological Sciences, 2005
The heterotrimeric G-protein alpha subunit has long been considered a bimodal, GTP-hydrolyzing switch controlling the duration of signal transduction by seven-transmembrane domain (7TM) cell-surface receptors.
