"
  • Chloride channels: This superfamily of channels consists of approximately 13 members. They include ClCs, CLICs, Bestrophins and CFTRs. These channels are non-selective for small anions; however chloride is the most abundant anion, and hence they are known as chloride channels.[citation needed]
  • Potassium channels[citation needed]
    • Voltage-gated potassium channels e.g., Kvs, Kirs etc.
    • Calcium-activated potassium channels e.g., BKCa or MaxiK, SK, etc.
    • Inward-rectifier potassium channels
    • Two-pore-domain potassium channels: This family of 15 members form what is known as leak channels, and they display Goldman-Hodgkin-Katz (open) rectification.
