{wiki=Cation_channel_superfamily}
The cation channel superfamily refers to a diverse group of ion channels that primarily conduct cations, which are positively charged ions such as sodium (Na+), potassium (K+), calcium (Ca²+), and magnesium (Mg²+). These channels play critical roles in various physiological processes, including the regulation of cellular excitability, muscle contraction, neurotransmitter release, and signal transduction.
