靶點詳情

功能：

Specifically phosphorylates the activated forms of G protein-coupled receptors. GRK4-alpha can phosphorylate rhodopsin and its activity is inhibited by calmodulin; the other three isoforms do not phosphorylate rhodopsin and do not interact with calmodulin. GRK4-alpha and GRK4-gamma phosphorylate DRD3. Phosphorylates ADRB2.
基因功能參考文獻：
1. GRK4 gene variants in humans (GRK4 A>65L, A>142V, and A>486V) are associated with Hypertension in several but not all ethnic groups. GRK4 gene variants impair the function of D1R and D3R and abet the function of AT1R. These lead to enhancement of renal sodium reabsorption and impaired ability to excrete a sodium load that eventually leads to hypertension. Acknowledgments PMID: 27045027
2. On normal salt diet, renal CuZnSOD and ECSOD proteins were similar but renal MnSOD was lower in hGRK4g486V than Non-T mice and remained low on high salt diet. hGRK4gammawild-type mice were normotensive and hGRK4g142V mice were hypertensive but both were salt-resistant and in normal redox balance. Chronic tempol treatment partially prevented the salt-sensitivity of hGRK4g486V mice. PMID: 28189851
3. A novel function of GRK4 on triggering a p53-independent cellular senescence, which involves an intricate signaling network. PMID: 28912086
4. the association between GRK4(142V) and a larger decrease in blood pressure with angiotensin receptor blockers in hypertensive patients. PMID: 25732908
5. Subgroup analysis for ethnicity showed that rs1024323 locus of GRK4 gene was associated with hypertension in Caucasians (OR =1.826, 95% CI =1.215-2.745, P=0.004) but not in East Asians and Africans. [meta-analysis] PMID: 26730182
6. Thus, we provided new insight into the function of GRKs in agonist-unstimulated GPCR trafficking using a recombinant AM1 receptor and further determined the region of the CLR C-tail responsible for this GRK function. PMID: 26820533
7. hGRK4gamma(142V) phosphorylates histone deacetylase type 1 and promotes its nuclear export to the cytoplasm, resulting in increased AT1R expression and greater pressor response to angiotensin II. PMID: 26667412
8. A high sodium intake markedly increased the obesity risk in variants of GRK4 A486V regardless of sex amongst Korean children. PMID: 25768006
9. The C-terminal region of FMRP interacts with a domain of GRK4 mRNA that is folded in four stem loops. PMID: 26250109
10. GRK4alpha is more similar to GRK2 than GRK6. A fully ordered kinase C-tail reveals interactions linking the C-tail with important determinants of kinase activity, including the alphaB helix, alphaD helix, and the P-loop PMID: 26134571

26. Genetic variation in Gprotein-coupled receptor kinase 4 was associated with hypertension in northern Han Chinese. PMID: 17044852
27. We conclude that the elevated blood pressure of hGRK4gamma A142V transgenic mice is due mainly to the effect of hGRK4gamma A142V transgene acting via D(1)R and increased ROS production is not a contributor. PMID: 17259440
28. This evidence suggests the kinase domain of GRK4gamma is responsible for GPCR regulation and GRK4 binding to inactive Galpha(s) and Gbeta may explain the constitutive activity of GRK4gamma towards Galpha(s)-coupled receptors. PMID: 18190783
29. The GRK4 Ala142Val polymorphism did not contribute to the phenotypes in renal handling of sodium PMID: 18413491
30. The potential implication of GRK4 promoter variation in blood pressure control in humans is unmistakable. PMID: 18711006

亞細胞定位：

Cytoplasm. Cytoplasm, cell cortex. Note=Both at the cell surface and dispersed in the cytoplasm under basal conditions. Receptor stimulation results in the internalization of GRK4 to the perinuclear area, where colocalization with DRD3 is observed strongly at 5 and 15 minutes. DRD3 and GRK4 colocalize in lipid rafts of renal proximal tubule cells.
