In the GluR1 glutamate receptor subunit a glutamine to histidine point mutation suppresses inward rectification but not calcium permeability.
???displayArticle.abstract???
Recent papers have described glutamine to arginine point mutations of the cloned AMPA/Kainate receptor subunits that alter current-voltage relationship and suppress Ca2+ permeability, thus linking these two characteristics. We describe a glutamine to histidine mutation at the same position, which alters current-voltage relationship but retains Ca2+ permeability, thus dissociating the two properties.
