anomalous rectifier channel

biology
Also known as: IIR channel, inward rectifier channel

Quick Summary

Anomalous rectifier channels are a type of ion channel found in cell membranes. These protein channels are crucial for regulating the flow of charged ions, such as potassium, across the cell membrane.1

Unlike typical channels that open with depolarization, anomalous rectifier channels close when the membrane depolarizes and open when it hyperpolarizes. This unique characteristic allows for an unusual inward diffusion of potassium ions, which prolongs the depolarization of the neuron and contributes to the generation of long-lasting nerve impulses. These channels play a vital role in the electrical signaling within the nervous system.21
