Explanation of structural basis of inward rectification

Published in Proteomics Weekly, March 3rd, 2003

"Inward rectifier K+ channels govern the resting membrane voltage in many cells," researchers in the United States report.

"Regulation of these ion channels via G protein-coupled receptor signaling underlies the control of heart rate and the actions of neurotransmitters in the central nervous system. We have determined the protein structure formed by the intracellular N- and C termini of the G protein-gated inward rectifier K+ channel GIRK1 at 1.8 Angstrom resolution.

"A cytoplasmic pore, conserved among inward rectifier K+ channels, extends the ion pathway to 60 Angstrom, nearly twice the length of a canonical transmembrane K+ channel," wrote M....
