Angiotensin II type 1 receptor

Organism

Rat1 2, Human3

Functional implication

Agonist stimulation leads to translocation to caveolae1 or non-caveolin lipid raft2 or has no effect on localization3, Caveolin-binding mutation reduces the plasma membrane expression, agonist-dependent internalization and phospholipase C production3, Microtubules are essential in translocating the AT1 receptor to caveolae4, Receptors movement into caveolae is necessary for ROS production, Rac1 activation, Sos-1 tyrosine phosphorylation, ROS-dependent Akt phosphorylation and VSMC hypertrophy5
