  • 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.
  • 基因功能参考文献：
    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

    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

    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

  • 亚细胞定位：
    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.
