In biochemistry and signal transduction, G-protein-coupled receptor kinases are a "family of serine-threonine kinases that are specific for G-protein-coupled receptors. They are regulatory proteins that play a role in G-protein-coupled receptor densensitization."[1]
Pharmacogenomics
Regarding the treatment of heart failure, there is conflicting evidence whether beta-blockers medications are as effective in African-American patients as in Anglo patients.[2] This may be due to a polymorphism in African-American patients of the G protein–coupled cell surface receptor kinase (GRK5) (OMIM) that confers a natural "genetic beta-blockade".[3]
