text: *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.
  *Potassium channels
  **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.
  *Sodium channels
  ** Voltage-gated sodium channels (NaVs)
  ** Epithelial sodium channels (ENaCs)
  *Calcium channels (CaVs)
  *Proton channels
  **Voltage-gated proton channels
  *Non-selective cation channels: These non-selectively allow many types of cations, mainly Na, K and Ca, through the channel.
  **Most transient receptor potential channels
