      Drug Name Diazoxide Hydralazine
      Mechanism Hypotensive effects
ATP-sensitive inward rectifier potassium channel  Inducer
Antihypertensive agent
Membrane copper amine oxidase  Inhibitor
      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.

Gene Name AOC3
Uniprot ID AOC3_HUMAN
KEGG Pathway hsa:8639
Protein Family Copper/topaquinone oxidase family
Protein Function
Cell adhesion protein that participates in lymphocyte extravasation and recirculation by mediating the binding of lymphocytes to peripheral lymph node vascular endothelial cells in an L-selectin-independent fashion. Has semicarbazide-sensitive (SSAO) monoamine oxidase activity. May play a role in adipogenesis.
