Stereocilin

Length. 1809 aa. Localization. Outer hair cell stereocilia tips and along lateral surface. GPI-anchored to outer membrane. Function.

  • Horizontal top connectors (HTC) — couples adjacent stereocilia into mechanical row
  • Tectorial attachment — couples tallest row to tectorial membrane
  • Loss → bundle disorganization + failed TM coupling → mild-moderate sensorineural hearing loss (DFNB16).
