<unk> ly rectifing potassium channels (Kir, IRK) are potassium selective<unk>  channels. To date, seven subfamilies have been identified in various mammalian cell types. They are the targets of multiple toxins, and malfunction of the channels has been implicated in several diseases.
Inward-rectifier potassium ion channel
Voltage-dependent calcium channel
Sodium calcium exchanger
Calcium channel
Tandem pore domain potassium channel
Cyclic nucleotide-gated ion channel
Light-gated ion channel
Chloride channel
