Summary: 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. Predicted to be located in Golgi apparatus and endosome. Predicted to be active 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
