KATP channels

ATP-sensitive potassium channels are hetero-octamers composed of four pore-forming and four regulatory subunits. The two pore-forming and the two regulatory genes are expressed in many tissues. In beta cells, the channel is composed of Kcnj11 ((Kir6.2) pore-forming and the Abcc8 (Sur1) regulatory subunits. The pore-forming subunit is an inward rectifier; the regulatory subunit belongs to the C-branch of the ATP-binding cassette (ABC) transporter superfamily with affinity for sulfonylurea. More information can be found in PMIDs 16545085, 16897043. The two genes are listed with aliases in parentheses, full names and links to gene report pages:

Kcnj11 (Kir6.2) – potassium voltage-gated channel subfamily J member 11
Abcc8 (Sur1) – ATP binding cassette subfamily C member 8
