Allosteric switching of Ca2+ permeability in the lysosomal ion channel TPC2 underpins biased agonist activation
This article shows that this plasticity is governed by a distal allosteric network that allows TPC2 to discriminate between agonists and generate specific lysosomal ion fluxes, and Mutant channels exhibit enhanced Ca²⁺ permeability and adopt a co-activated-like state.
