LincNEAT1 Encoded‐NEAT1‐31 Promotes Phagocytosis by Directly Activating the Aurora‐A–PI3K–AKT Pathway

Advanced Science, EarlyView.
LincNEAT1 Encoded‐NEAT1‐31 micropeptide directly binds with Aurora‐A and enhanced AKT pathways to pormotes phagocytosis against multi cancer cells. Abstract Macrophages play vital roles in innate and adaptive immunity, and their essential functions are mediated by phagocytosis and antigen presentation.

PROS1‐MERTK Axis Drives Tumor Microenvironment Crosstalk and Progression in Papillary Thyroid Microcarcinoma

Advanced Science, EarlyView.
Identifying biomarkers associated with PTC, particularly those related to PTMC progression, is crucial for precise risk stratification and treatment planning. This study utilized single‐cell RNA sequencing on 19 surgical tissue specimens, confirmed PROS1/MERTK axis as a critical component of the cellular microenvironment and a key regulatory mechanism ...

RIG‐I‐Inducing Small Molecules Potently Inhibit HMA‐Resistant AML Through Igniting the Overloaded dsRNA Arsenal

Advanced Science, EarlyView.
This study reveals a novel mechanism of resistance to DNA hypomethylating agents (HMAs) in acute myeloid leukemia (AML), and identifies all‐trans retinoic acid (ATRA) and tamibarotene (TAM) as potent agents that overcome HMA resistance by reactivating the interferon anticancer immune response. The findings offer promising therapeutic strategies for HMA‐

G-protein-coupled receptor kinases and the heart

Trends in Cardiovascular Medicine, 1995
The family of G-protein-coupled receptors includes many well-studied members, such as the adrenergic and the muscarinic acetylcholine receptors. These receptors are regulated by multiple mechanisms that serve to adapt their expression and their function to a rapidly changing environment.

Regulation of G Protein-Coupled Receptor Kinases

Trends in Cardiovascular Medicine, 2000
G protein-coupled receptor kinases (GRKs) specifically interact with the agonist-activated form of G protein-coupled receptors (GPCRs) to effect receptor phosphorylation and desensitization. Recent studies demonstrate that GRK function is a highly regulated process, and it is perhaps in this manner that a handful of GRKs (7 have been identified to date)

Regulation of G Protein-Coupled Receptor Kinases by Phospholipids

Current Medicinal Chemistry, 2012
G protein coupled-receptor (GPCR) kinases (GRKs) initiate the deactivation of GPCRs by phosphorylating their cytoplasmic loops and C-terminal tails. They are regulated not only by allosteric interactions with activated GPCRs, but also by the membrane environment itself.

G-protein-coupled receptor regulation: role of G-protein-coupled receptor kinases and arrestins

Canadian Journal of Physiology and Pharmacology, 1996
G-protein-coupled receptors (GPCRs) represent a large family of proteins that transduce extracellular signals to the interior of cells. Signalling through these receptors rapidly desensitized primarily as the consequence of receptor phosphorylation, but receptor sequestration and downregulation can also contribute to this process.

G protein—coupled receptor kinases

Cell, 1993
G protein‐coupled receptor kinases (GRKs) constitute a family of six mammalian serine/threonine protein kinases that phosphorylate agonist-bound, or activated, G protein‐coupled receptors (GPCRs) as their primary substrates. GRK-mediated receptor phosphorylation rapidly initiates profound impairment of receptor signaling, or desensitization.

Targeting G protein-coupled receptor kinases to their receptor substrates

Journal of Membrane Biology, 1997
Membrane association is essential for GRK function and because of this the GRKs have evolved complex regulatory mechanisms for associating with the membrane. Although the GRKs are highly homologous, each kinase utilizes a distinct mechanism for associating with the membrane, which makes it unique within the family.
