stereocilia coupling link stereocilia tip link GO:0002140 hjd A stereocilia link that is formed by a fine filament running more or less vertically upward from the tip of each shorter stereocilium to attach at a higher point on its adjacent taller neighbor. Tilting the bundle puts tension on the filaments, which pull on mechanically gated ion channels in the membrane of the stereocilia. 2009-05-06T10:28:10Z cellular_component
