Retrovirally mediated transfer of a G protein-coupled receptor kinase (GRK) dominant-negative mutant enhances endogenous calcitonin receptor signaling in Chinese hamster ovary cells. GRK inhibition enhances expression of receptors and receptor mRNA.

Abstract excerpt

G protein-coupled receptor kinases (GRKs) initiate pathways leading to agonist-dependent phosphorylation and desensitization of G protein-coupled receptors. However, the role of GRKs in modulation of signaling properties of native receptors has not been clearly defined. Here we addressed this que...
