Previous GeneCards Identifiers for KCNJ15 Gene
Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. The encoded protein has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Eight transcript variants encoding the same protein have been found for this gene.

GeneCards Summary for KCNJ15 Gene
KCNJ15 (Potassium Inwardly Rectifying Channel Subfamily J Member 15) is a Protein Coding gene. Diseases associated with KCNJ15 include Hypomagnesemia 4, Renal and Vitreoretinal Degeneration, Snowflake Type. Among its related pathways are Dopamine-DARPP32 Feedback onto cAMP Pathway and Inwardly rectifying K+ channels. Gene Ontology (GO) annotations related to this gene include potassium channel activity and inward rectifier potassium channel activity. An important paralog of this gene is KCNJ10.
UniProtKB/Swiss-Prot Summary for KCNJ15 Gene
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.
The inward-rectifier potassium channel family (also known as 2-TM channels) include the strong inward-rectifier channels (Kir2.x), the G-protein-activated inward-rectifier channels (Kir3.x) and the ATP-sensitive channels (Kir6.x), which combine with sulphonylurea receptors.
