Binds cholesterol and may regulate the distribution and homeostasis of cholesterol in hair cells . May play a role in angiogenesis .
Subcellular locations: Lysosome membrane, Endoplasmic reticulum membrane
Localizes to the stereocilia and the apical region of hair cell, apparently around and just below the cuticular plate (By similarity). Co-localized with cholesterol in the stereocilia (By similarity).
Highly expressed in the auditory hair cells.
