AGTR1
AGTR1 (Angiotenzinski II receptor, tip 1, AT1 receptor) je angiotenzinski receptor. On ima simpatomimetičko dejstvo i reguliše sekreciju aldosterona. On je značajan efektor kontrole krvnog pritiska i zapremine u kardiovaskularnom sistemu. Antagonisti angiotenzin II receptora su lekovi za hipertenziju, dijabetesnu nefropatiju i srčanu insuficijenciju. AGTR1 je najbolje istraženi angiotenzinski receptor.
Mehanizam
[уреди | уреди извор]Angiotenzinski receptori se aktiviraju vazokonstriktivnim peptidom angiotenzin II. Aktivirani receptor se spreže sa Gq/11, aktivira fosfolipazu C i povišava koncentraciju citosolnog Ca2+, čime se zatim inicira ćelijski respons kao što je stimulacija proteinske kinaze C. Aktivirani receptor takođe inhibira adenilat ciklazu i razne tirozinske kinaze.[1]
