CC   -!- FUNCTION: Voltage-sensitive motor protein that drives outer hair cell
CC       (OHC) electromotility (eM) and participates in sound amplification in
CC       the hearing organ. Converts changes in the transmembrane electric
CC       potential into mechanical displacements resulting in the coupling of
CC       its expansion to movement of a charged voltage sensor across the lipid
CC       membrane. The nature of the voltage sensor is not completely clear, and
CC       two models compete. In the first model, acts as an incomplete
CC       transporter where intracellular chloride anion acts as extrinsic
CC       voltage sensor that drives conformational change in the protein which
CC       is sufficient to produce a length change in the plane of the membrane
CC       and hence in the length of the OHC. The second model in which multiple
CC       charged amino acid residues are distributed at the intracellular and
CC       extracellular membrane interfaces that form an intrinsic voltage
CC       sensor, whose movement produces the non-linear capacitance (NLC).
CC       However, the effective voltage sensor may be the result of a hybrid
CC       voltage sensor, assembled from intrinsic charge (charged residues) and
CC       extrinsic charge (bound anion). Notably, binding of anions to the
CC       anion-binding pocket partially neutralizes the intrinsic positive
CC       charge rather than to form an electrically negative sensor, therefore
CC       remaining charge may serve as voltage sensor that, after
CC       depolarization, moves from down (expanded state) to up (contracted)
CC       conformation, which is accompanied by an eccentric contraction of the
CC       intermembrane cross-sectional area of the protein as well as a major
CC       increase in the hydrophobic thickness of the protein having as
CC       consequences the plasma membrane thickening and the cell contraction
CC       after membrane depolarization. The anion-binding pocket transits from
CC       the inward-open (Down) state, where it is exposed toward the
CC       intracellular solvent in the absence of anion, to the occluded (Up)
CC       state upon anion binding. Salicylate competes for the anion-binding
CC       site and inhibits the voltage-sensor movement, and therefore inhibits
CC       the charge transfer and electromotility by displacing Cl(-) from the
CC       anion-binding site and by preventing the structural transitions to the
CC       contracted state. In addition, can act as a weak Cl(-)/HCO3(-)
CC       antiporter across the cell membrane and so regulate the intracellular
CC       pH of the outer hair cells (OHCs), while firstly found as being unable
CC       to mediate electrogenic anion transport. Moreover, supports a role in
CC       cardiac mechanical amplification serving as an elastic element to
CC       enhance the actomyosin- based sarcomere contraction system.
