Predicted to enable cytoskeletal protein-membrane anchor activity. Predicted to be a structural constituent of cytoskeleton. Involved in several processes, including nervous system development; paranodal junction maintenance; and protein localization to paranode region of axon. Located in juxtaparanode region of axon; paranode region of axon; and postsynaptic density. Colocalizes with axolemma. Is expressed in several structures, including central nervous system; notochord; paraxial mesenchyme; and retina. Orthologous to human EPB41L3 (erythrocyte membrane protein band 4.1 like 3).
