| Abstract: | Background Prior to this report, members of the inward rectifier family, or Kir, have been found only in eukaryotes. Like most K+ channels, the pore-forming part of the protein is formed by four identical, or closely related, subunits. Each subunit contains
a transmembrane M1-P-M2 motif that is followed by a relatively large C-terminus region unique to Kir's. |
