Motor protein in organ of coi ?

Ans. is d i.e., Myosin The inner hair cells of organ of coi have 50-200 ciliated structure called stereocilia. The top of each stereocilium is linked to the side of next adjacent higher stereocilium by means of a thin filamentous strucuture called the tip-link. Mechanically gated ion channels are located at these attachment points on the sides of stereocilia. Each stereocilium comprises of several actin filaments encased by a plasma membrane. The opening and closing of the ion channels is accomplished through the binding and unbinding of proteins at terminal ends of the tip links with a group of channel motor proteins (myosin) which move up and down the actin filaments of stereocilia.
