type-specific functions Published date November 1, 2022 Abstract G-protein coupled receptor kinases (GRKs However, there is growing evidence that GRKs can also control cellular functions beyond GPCR regulation Immune cells commonly express two to four members of the GRK family (GRK2, GRK3, GRK5, GRK6) simultaneously In particular, we are missing comprehensive studies comparing the role of this GRK interplay for (a) To address this issue, we generated mouse models of single, combinatorial and complete GRK knockouts

After ligand binding, GPCRs are phosphorylated by different GPCR kinases (GRKs) at distinct sites on However, the molecular mechanisms by which individual GRKs are selectively targeted to GPCRs have been domain-containing (COMMD) 3 and 8 (COMMD3/8 complex) functions as an adaptor that recruits a specific GRK Authors Taiichiro Shirai , Akiko Nakai , Kazuhiro Suzuki Tags B cell migration , COMMD3/8 complex , GRK

She recently led a project that demonstrated the GPCR kinases (GRKs) can translocate to endosomes, and that the subcellular localization of the GRKs affects a GPCR's biased signaling profile.

initial project to identify and clone taste receptors was unsuccessful, but led to the identification of GRK5 and continued focus on GRKs (particularly GRKs 4,5,6) and arrestins as GPCR regulators and as mediators regulation of G protein-coupled receptor signaling particularly by the G protein-coupled receptor kinase (GRK

differential signaling outputs of biased agonists, and demonstrating the ligand specificity behind GRK

By contrast, ACKR3 recruits GPCR kinases (GRKs) and β-arrestins and promiscuously responds to CXCL12,

GPCR kinases (GRKs) can regulate GPCR activation. Heme also activates GRK2. GRK2 inhibitors like paroxetine restore functions. GRK2 activation via TLR9 prevented actin reorganization, implicating histone deacetylases (HDACs). and a novel TLR-activated GRK2 pathway impairing cytoskeletal organization. Simultaneous GRK2/HDAC inhibition rescues susceptibility to infection after tissue injury.

They discussed various modulatory elements, such as RAMPs, G proteins, and GRKs, with Arthur recounting

as a biomarker of oral squamous cell carcinoma (OSCC) by regulating the signaling pathway of miR-19a/GRK6 Wang , Danhua Ma , He Zhang , Jiayan Fan , Hongyan Gao , Xinyu Xia , Wei Wu , Yuyuan Shi Tags GPCR , GRK6

analysis and luciferase assays were performed to establish a potential signaling pathway of miR-19a/GRK6 Results: We found that miR-19a, GPR39 mRNA and PKC mRNA were upregulated while GRK6 mRNA was downregulated Moreover, in silico analysis confirmed a potential binding site of miR-19a on the 3'UTR of GRK6 mRNA, and the subsequent luciferase assays confirmed the molecular binding between GRK6 and miR-19a. We further identified that the over-expression of miR-19a could regulate the signaling between GRK6,

Ribas has also described a new protective role of G protein-coupled receptor kinase 2 (GRK2), a known
