UniProtKB - P84189 (NDBH1_TITSE)
Protein
Hypotensin-1
Gene
N/A
Organism
Tityus serrulatus (Brazilian scorpion)
Status
Functioni
Agonist of the B2 bradykinin receptor (BDKRB2). Potentiates the hypotensive effect of bradykinin (BK) and induces a direct vasorelaxing effect, independently of BK, by endothelium- and nitric oxide (NO)-dependent mechanisms in rat aortic ring preparations.2 Publications
Miscellaneous
Does not inhibit the angiotensin-converting enzyme (ACE).1 Publication
