n. a serine/threonine intracellular enzyme whose function is to inactivate beta adrenoreceptors. Specifically, the kinase inhibits these receptors from activating messengers within the nerve cell. As a result, the cell desensitizes itself from being overstimulated by epinephrine.
BETA-ADRENERGIC RECEPTOR KINASE (BARK): "Primarily, BARK is an enzyme which prevents the beta adrenergic receptor from being overstimulated."
