Term Detail
GO term:alpha2-adrenergic receptor activity
Synonym: alpha2 adrenoceptor
GO id:GO:0004938
Definition:Combining with epinephrine or norepinephrine to initiate a change in cell activity via activation of a G protein, with pharmacological characteristics of alpha2-adrenergic receptors; the activity involves transmitting the signal to the Gi alpha subunit of a heterotrimeric G protein.
