1 Since Gd3+ has about the same ionic radius as Ca2+, and since Ca2+ is normally transported across the sarcoplasmic reticulum membrane and accumulated within the vesicle, it is concluded that the increased charge density of the lanthanide ions is critical to the ion transport mechanism, resulting in their localization at the ATPase site and failure to be transported across the membrane.
