Beta-Adrenergic Receptor Kinase (BARK) is a critical enzyme in the regulation of beta-adrenergic receptor (beta-AR) signaling and receptor desensitization. It is a member of the AGC kinase family that includes protein kinase A (PKA), protein kinase C (PKC) and others. BARK is responsible for phosphorylating the carboxyl tail of beta-ARs, resulting in desensitization of the […]
