钾通道存在于大多数哺乳动物细胞中，它们参与了广泛的生理反应该基因编码的蛋白是一个完整的膜蛋白和内向整流型钾通道编码的蛋白质更倾向于让钾流入细胞而不是流出细胞，它可能参与建立神经元和肌肉组织的动作电位波形和兴奋性。该基因突变与安徒生综合征有关，其特征是周期性麻痹、心律失常和畸形。[由RefSeq提供，2008年7月]
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, probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues. Mutations in this gene have been associated with Andersen syndrome, which is characterized by periodic paralysis, cardiac arrhythmias, and dysmorphic features. [provided by RefSeq, Jul 2008]
