ANK3 In skeletal muscle, required for costamere localization of DMD and betaDAG1. Membrane-cytoskeleton linker. May participate in the maintenance/targeting of ion channels and cell adhesion molecules at the nodes of Ranvier and axonal initial segments. Regulates KCNA1 channel activity in function of dietary Mg(2+) levels, and thereby contributes to the regulation of renal Mg(2+) reabsorption. Isoform 5: May be part of a Golgi-specific membrane cytoskeleton in association with beta-spectrin. Expressed in brain, neurons, muscles and other tissues. 5 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
