ADRA2B

Functionⁱ

Alpha-2 adrenergic receptors mediate the catecholamine-induced inhibition of adenylate cyclase through the action of G proteins. The rank order of potency for agonists of this receptor is clonidine > norepinephrine > epinephrine = oxymetazoline > dopamine > p-tyramine = phenylephrine > serotonin > p-synephrine / p-octopamine. For antagonists, the rank order is yohimbine > chlorpromazine > phentolamine > mianserine > spiperone > prazosin > alprenolol > propanolol > pindolol.1 Publication

Involvement in diseaseⁱ

Epilepsy, familial adult myoclonic, 2 (FAME2)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA form of cortical myoclonic tremor with epilepsy, a syndrome characterized by cortical myoclonus and variable occurrence of epileptic seizures. Usually, myoclonic tremor is the presenting symptom, characterized by tremulous finger movements and myoclonic jerks of the limbs increased by action and posture. In a minority of patients, seizures are the presenting symptom; both complex partial as well as generalized tonic clonic seizures are described. Some patients exhibit mild cognitive impairment.
