Protein: Ankyrin-3 (ANK-3) (Ankyrin-G) (G5E8K5)
Organism: Mus musculus (Mouse)
Function: 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 (By similarity). In skeletal muscle, required for costamere localization of DMD and betaDAG1. Regulates KCNA1 channel activity in function of dietary Mg(2+) levels, and thereby contributes to the regulation of renal Mg(2+) reabsorption.
Subcellular location: Cytoplasm, cytoskeleton {ECO:0000250|UniProtKB:Q12955}. Cell projection, axon {ECO:0000250|UniProtKB:O70511}. Cell membrane, sarcolemma {ECO:0000250|UniProtKB:Q12955}. Postsynaptic cell membrane {ECO:0000250|UniProtKB:O70511}. Lysosome {ECO:0000269|PubMed:9060470}. Cell membrane, sarcolemma, T-tubule {ECO:0000250|UniProtKB:O70511}. Note=In skeletal muscle, localized at costameres and neuromuscular junctions. In bone marrow-derived macrophages, isoforms 2 and 3 are associated with lysosomes.
