FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. Defects in this gene may be a cause of J-wave syndromes and sudden infant death syndrome (SIDS). [provided by RefSeq, May 2012]
PHENOTYPE: Mice homozygous for a targeted null mutation exhibit sudden cardiac death due to dysregulation of the vascular tonus in the coronary arteries, and exhibit a phenotype resembling Prinzmetal (or variant) angina in humans. [provided by MGI curators]
