This gene has 1 transcript (splice variant), 186 orthologues and 15 paralogues. Restricted expression toward brain (RPKM 8.9).

Summary

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. It associates with another G-protein-activated Potassium Channel to form a heteromultimeric pore-forming complex. [provided by RefSeq, Jul 2008]
