Immunopharmacology Comments
GRK2 (βARK1) expression and activity are downregulated in lymphocytes from RA patients [8]. In healthy leukocytes, pro-inflammatory cytokines reduce GRK2 expression

Physiological Consequences of Altering Gene Expression
Increased GRK2 protein and mRNA levels are associated with increased myocardial GRK activity in human heart failure.
Species:  Human
Tissue:  Cardiac tissue.
Technique:  qPCR, Western blotting.
References:  2-3,13-14
Germline ablation of the GRK2 gene produces embryonic lethality, with embryos displaying cardiac abnormalities.
Species:  Mouse
Tissue: 
Technique:  Gene knock-out.
References:  6
Physiological Consequences of Altering Gene Expression Comments
The essential role of GRK2 in embryonic development may not be due to its GPCR kinase activity, as mice with cardiac-specific ablation of GRK2 develop normally [5].
