      Drug Name Diazoxide Riociguat
      Mechanism Hypotensive effects
ATP-sensitive inward rectifier potassium channel  Inducer
Hypotensive effects
Soluble guanylyl cyclase  Agonist
      Key Mechanism Factor 1
Factor Name Inward rectifier potassium channel Structure Sequence
Protein Family Inward rectifier-type potassium channel (TC 1.A.2.1) family
Protein Function
This receptor is controlled by G proteins. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by extracellular barium (By similarity). Subunit of ATP-sensitive potassium channels (KATP). Can form cardiac and smooth muscle-type KATP channels with ABCC9. KCNJ11 forms the channel pore while ABCC9 is required for activation and regulation.
