Bradikininski receptor B2 je G-protein spregnuti receptor bradikinina. Njega kodira BDKRB2 gen kod čoveka.
Mehanizam
B2 receptor je G protein-spregnuti receptor. Pretpostavlja se da je spregnut sa Gq, dok Gi. Gq stimuliše fosfolipazu C i povišava koncentraciju Intracelularnog slobodnog kalcijuma i Gi inhibira adenilat ciklazu. Pored toga, receptor stimuliše puteve mitogenom-aktiviranih proteinskih kinaza. On je široko rasprostranjen i konstitutivno izražen u zdravim tkivima.
B2 receptor formira kompleks sa angiotenzin konvertujućim enzimom (ACE), i stoga se smatra da učestvuje u razmeni informacija između renin-angiotenzinskog sistema (RAS) i kinin-kalikreinskog sistema (KKS). Heptapeptid angiotenzin 1-7 (A1-7) takođe pojačava dejstvo bradikinina na B2 receptore.[1]
Kalidin takođe dejstvuje kroz B2 receptor.
Funkcija
Bradikinin je peptid sa 9 aminokiselina koji proizvodi mnogobrojne response kao što su vazodilatacija, edemi i spazam glatkih mišića.
