Composition of the sarcolemmal KATP channel and location of various subunits in various tissues. The channel is a functional octamer of four Kir6.x subunits (generating the channel pore) and four sulfonylurea receptor (SUR) subunits that generate the regulatory subunit. TMD is transmembrane domain, NBF is nucleotide – binding fold, and M1 and M2 are transmembrane helices.
