WebVoltage-gated ion channels Voltage-gated ion channels, which respond to electrical activity and are essential for the generation of action potentials, are among the most common types of ion channels in neurons. Specifically, action potentials are generated by current moving through voltage-gated sodium and potassium ion channels. WebIon channels and G protein–coupled receptors (GPCRs) are regulated by lipids in their membrane environment. Structural studies combined with biophysical and molecular simulation investigations reveal interaction sites for specific lipids on membrane protein structures. For K channels, PIP2 plays a key role in regulating Kv and Kir channels. … granite memorials edmonton
