Small potassium current channels (SK2 channels, KCNN2 tetramers) in outer hair cells (OHCs) open in response to cytosolic calcium and transport potassium ions from the cytosol to the extracellular region, resulting in hyperpolarization and inhibition of contraction of the OHC (inferred from the mouse homolog).
