2.7.11.16 malfunction depletion of endogenous GRK2 enhances canonical signaling 705737 2.7.11.16 malfunction enzyme deficiency contributes to the pathogenesis of Alzheimer's disease by influencing the hyperphosphorylation of tau through the activation of glycogen synthase kinase 3beta 761592 2.7.11.16 malfunction enzyme dysfunction is associated with congenital heart defects 762419 2.7.11.16 malfunction GRK5 or GRK6 knockdown has no effect on C3aR (G protein coupled receptors for C3a) desensitization, but causes a significant decrease in C3a-induced mast cell degranulation. GRK5 or GRK6 knockdown render mast cells more responsive to C3a for ERK1/2 phosphorylation 726276 2.7.11.16 malfunction GRK5-depleted cells are more sensitive to undergoing cell death from polo-like kinase 1 (PLK1) inhibition, and this increased susceptibility corresponds to decreased NPM1 phosphorylation. Conversely, cells with higher GRK5 levels exhibit reduced sensitivity to PLK1 inhibition 725471 2.7.11.16 malfunction inhibition of vascular smooth muscle GRK2 enhances beta-adrenergic receptor signaling 684355 2.7.11.16 malfunction isoform GRK6 knockdown promotes cell migration and invasion in lung adenocarcinoma cells 761095 2.7.11.16 malfunction knockdown of GRK2 or GRK3 expression using shRNA causes a more sustained Ca2+ mobilization, attenuated C3aR (G protein coupled receptors for C3a) desensitization, and enhanced degranulation as well as ERK1/2 phosphorylation when compared to shRNA control cells 726276 2.7.11.16 malfunction knockdown of GRK5 expression leads to G2/M arrest, characterized by a prolonged G2 phase, which can be rescued by expression of wild type but not catalytically inactive GRK5 725509 2.7.11.16 malfunction knockdown of GRK5 in osteosarcoma cells inhibits DNAdamage-induced apoptosis via a p53-mediated mechanism 725394
