Members of this family form ion channel pores that allow potassium ions to pass into a cell. The encoded protein belongs to a subfamily of low signal channel conductance proteins that have a low dependence on potassium concentration. Mutations in this gene are associated with snowflake vitreoretinal degeneration. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Feb 2010]. * **UniProt Summary**: 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. KCNJ13 has a very low single channel conductance, low sensitivity to block by external barium and cesium, and no dependence of its inward rectification properties on the internal blocking particle magnesium. |IRK| |inward rectifier potassium channel activity| |potassium ion import across plasma membrane| |inorganic cation import across plasma membrane| |inorganic ion import across plasma membrane| |import across plasma membrane| |potassium ion transmembrane transport| |potassium ion transport| |monovalent inorganic cation transport| |regulation of ion transmembrane transport| |inorganic cation transmembrane transport| |regulation of transmembrane transport| |cation transmembrane transport| |metal ion transport| |inorganic ion transmembrane transport| |import into cell| |regulation of ion transport| |cation transport| |ion transmembrane transport| |transmembrane transport| |ion transport| |regulation of transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp535|Trimetrexate 0.03μM R08 exp535]]|-2.03| |[[:results:exp515|PU-H71 1μM R08 exp515]]|-1.8| |[[:results:exp362|GSK-J4 1μM R07 exp362]]|-1.74| No correlation found to any other genes in chemogenomics.
