    basic FUNCTION
  • involved in blood pressure regulation
  • involved in the activation of dephosphorylating enzymes
  • stimulating a phosphotyrosine phosphatase which inhibits guanylate cyclase
  • involved in brain development and in trophic maintenance of cerebral neuronal connections
  • protecting from severe acute lung injury induced by acid aspiration or sepsis
  • AGTR1 and AGTR2, in the striatum exert an opposite effect on the modulation of dopamine synthesis rather than dopamine release
  • potential role in the cerebellar function
  • modulate mitochondrial respiration
  • AGTR1 and AGTR2 reciprocally regulate basal perfusion of muscle microvasculature
  • AGTR2 activity is required for normal microvascular responses to insulin
  • opposing effects of AGTR1 and AGTR2 on VEGF-driven angiogenesis converge on the regulation of activity of RHOA-ROCK-dependent endothelial cells migration
  • induce production of nitric oxide (NO), which may interact with ROS and modulate AGTR1 signaling
  • AGTR2-mediated effects may be implicated in the physiological maturation process of the heart
  • plays an important role in arterial pressure regulation and may modulate T cell activation and renal cytokine production during pregnancy
  • AGTR2 signaling positively regulates myoblast differentiation and potentiates skeletal muscle regenerative potential
  • may be involved in the control of sperm motility
  • plays a functional role in foetal development
  • AGTR2 on peripheral macrophages is a critical trigger for pain sensitization at the site of nerve injury
  • translocate to mitochondria and can contribute to reno-protective effects at early stages of diabetes
  • role of AGTR2 in improving lipid metabolism and preventing adiposity

    protein
  • interacting with NR1H4 (upregulates AGTR2 expression at a transcriptional level and play a role in the NR1H4-mediated inhibition of ERK activation via upregulation of PTPN6)
  • plays a significant role in T3-induced cardioprotection
  • AGTR2 inhibits ligand-induced AGTR1 signaling through the PKC-dependent pathway
  • AGTR2 regulates TGFBR2 expression and function via the nitric oxide pathway, which may be important in the control of renal tubulointerstitial fibrosis
  • IRF1 is one of the key transcriptional factors for the prevention of neointimal formation involving AGTR1, AGTR2
