KCNJ15

Potassium inwardly-rectifying channel, subfamily J, member 15, also known as KCNJ15 is a human gene, which encodes the K_ir4.2 protein.

Function

Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. K_ir4.2 is an integral membrane protein and inward-rectifier type potassium channel. K_ir4.2 has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Three transcript variants encoding the same protein have been found for this gene.
