G protein-coupled receptor kinase 4 is an enzyme that in humans is encoded by the GRK4 gene.
This gene encodes a member of the guanine nucleotide-binding protein (G protein)-coupled receptor kinase subfamily of the Ser/Thr protein kinase family. The protein phosphorylates the activated forms of G protein-coupled receptors thus initiating its deactivation. This gene has been linked to both genetic and acquired hypertension.
Midnight bright full moon shines the street is cold and quiet
An open window a naked room a creature's lonely cry
All your prayers they're useless now a man will turn to beast
Tonight until the morning comes he's ruled by evil greed
The ruler of the night the devil in disguise
He'll trap you all the way the victim of the change
In his cell the beast is kept but no chains can hold him back
Inside his blood is boiling hot his order is attack
If he hits you no use to run he fetches you to your doom
