Enables beta-2 adrenergic receptor binding activity and bradykinin receptor activity. Involved in several processes, including acute inflammatory response to antigenic stimulus; cellular response to hypoxia; and maintenance of blood-brain barrier. Located in plasma membrane. Used to study several diseases, including asthma; pancreatitis; pleurisy; portal hypertension; and pulmonary hypertension. Biomarker of high grade glioma; hypertension; myocardial infarction; and sciatic neuropathy. Human ortholog(s) of this gene implicated in asthma; chronic obstructive pulmonary disease; hypertension; and rhinitis. Orthologous to human BDKRB2 (bradykinin receptor B2).
