  • seven transmembrane domains that provide structural support for the formation of the ligand-binding pocket
  • two distinct calmodulin binding sites within AGTR1, at juxtamembrane regions of the N-terminus of the third intracellular loop (AAs 214-231) and carboxyl tail (AA 302-317)
  • C-terminus (CT) of AGTR1 directly and strongly bound to tubulin and the binding domains were mapped to two consecutive Lys residues at positions 310 and 311 in the CT membrane-proximal region of AGTR1 and the acidic CT of tubulin

    basic FUNCTION
  • major blood pressure regulator (activation of vascular growth)
  • activating phospholipase C and A2 inhibiting adenylate cyclase
  • fundamental role for AGT/AGTR1 in age-induced vascular dysfunction
  • may play a role in the pathophysiology of ischemic heart disease and could provide important targets for pharmaceutical interventions
  • G alpha(q/11)-coupled G protein-coupled receptor, inducing membrane blebbing by coupling to RHOA, Rho kinase, and myosin light chain kinase
  • AGTR1 and AGTR2, in the striatum exert an opposite effect on the modulation of dopamine synthesis rather than dopamine release
  • AGTR1 and AGTR2 reciprocally regulate basal perfusion of muscle microvasculature
  • AGTR1 activity restrains muscle metabolic responses to insulin via decreased microvascular recruitment and insulin delivery
  • opposing effects of AGTR1 and AGTR2 on VEGF-driven angiogenesis converge on the regulation of activity of RHOA-ROCK-dependent endothelial cells migration
  • role for AGTR1 on T lymphocytes to protect the kidney in the setting of hypertension by favorably modulating CD4(+) T helper cell differentiation
  • plays a pivotal role in the development of chronic heart failure (CHF), and is upregulated in a number of tissues owing, in part, to transcription factor nuclear factor kappa B (NFKB)
  • important role of the microtubule network in the cell surface transport of AGTR1
  • may be of crucial importance for the modulation of intestinal epithelial cells apoptosis
    signaling hormonal
    a component
    small molecule
  • interaction with DRD5 (mediates AGTR1 degradation via a ubiquitin-proteasome pathway)
  • ARAP1 may serve as a local modulator of vascular AGTR1 function
  • stimulation of the AGTR1 on catecholaminergic cells is required for the full development of angiotensin-dependent hypertension
  • GRK4, via regulation of arterial AGTR1 expression and function, participates in the pathogenesis of conduit vessel abnormalities in hypertension
  • NFKB and CREB1 are required for angiotensin II type 1 (AGTR1) receptor upregulation in neurons
  • SND1 increases angiotensin II type 1 receptor (AGTR1) levels by increasing AGTR1 mRNA stability
  • regulatory role of DRD4 on AGTR1 expression and function in in the vascular smooth muscle cell (VSMC)
  • AGTR1 is an ouabain-associating protein
  • cell & other
    activated by increased circulating AGT (this acivations are important mediators in the pathophysiology of several diseases characterized by sympatho-excitation)
    repressed by SIRT1 (downregulates AGTR1 expression in vascular smooth muscle cells)

  • contributing in association with ACE to the risk of coronary disease, to diabetic nephropathy and essential hypertension
  • to development of retinopathy of prematurity (ROP)
  • to fetal growth restriction syndrome
  • to pediatric hypertrophic cardiomyopathy with poor outcome
  • Variant & Polymorphism SNP , repeat , other

  • associated with progressive septal hypertrophy and left ventricular outflow tract obstruction in children with hypertrophic cardiomyopathy
  • association between SNPs and the development of ROP

    Therapy target
  • therapy for hypertension might be optimized by designing compounds that can target the AGTR1 and DRD5
  • targeting AGT/AGTR1 signaling could be a novel therapeutic for breast cancer
