Intellectual disability-associated UNC80 mutations reveal inter-subunit interaction and dendritic function of the NALCN channel complex

Abstract

The sodium-leak channel NALCN controls the resting membrane potentials of neurons. Here, the authors identified two subunits of NALCN, UNC80 and UNC79. Domains in UNC80, which are mutated in individuals with intellectual disability, interact to achieve the dendritic localization of NALCN complex.
