    basic FUNCTION
  • plays a role in potent and long-lasting vasoconstriction
  • mediates an increase in intracellular calcium and GnRH secretion
  • may enhance the proliferative potential of endometrial cells in a manner similar to that seen in vascular smooth muscle cells
  • EDNRA likely acts as a molecular mechanism by which HOXA10 promotes stromal cell growth and prostaglandin production in both the implantation window and decidua
  • endothelins, acting through EDNRA and/or EDNRB receptors, may play an important role in mediating pain resulting from activation of most trigeminal nerve branches
  • mediate the effect of EDN1 on total intracellular Ca2+ of human aortic vascular endothelial cells
  • plays an important role in the cerebrovascular physiology
  • play key roles in the maintenance of the vasculature by controlling the balance between vasoconstriction and vasodilation in response to hemodynamic stress
  • G-protein coupled receptor that mediates vasoconstriction of blood vessels

  • G protein alpha-subunit 3
  • histone acetyltransferase Tip60 and the histone deacetylase HDAC7
  • EDN1 and EDN2 bind to EDNRA with an affinity two orders of magnitude higher than that of EDN3
  • interacting with COPS5, an EDNRA-interacting protein (negatively regulates whole cell and cell surface levels of EDNRA)
  • link between EDN1 and EDNRA and myelination during oligodendrocyte differentiation
  • EDN1 activation of EDNRA signalled through ARF6, which is crucial for lipolysis
