    SUBCELLULAR LOCALIZATION     plasma membrane,junction,tight
    basic FUNCTION
  • compartimentalizing endolymph and providing support for the auditory neuroepithelium
  • tight junction specific obliteration of the intercellular space
  • its ability to be recruited to these junctions is crucial for the hearing process
  • creating charge specific channels in the paracellular space
  • regulates paracellular permeability at epithelial tight junctions (Thorleifsson 2009)
