    text
  • in the centriole
  • localized to the basal bodies of hair cells and supporting cells
  • localized to the ciliary basal body and/or centrioles in multiple tissues during development and in the functionally mature cochlea
    • basic FUNCTION
  • may playing a role in hearing, sight, obesity, and liver function
  • playing a role in intracellular trafficking
  • playing an important role in in cilia function and intra flagellar transport
  • centrosomal protein implicated in the assembly and maintenance of primary cilia
  • implicated in planar cell polarity signaling and the loss of outer hair cells causes potentially the majority of the hearing loss in Alström Syndrome
  • role in the regulation of cilium-dependent planar cell polarity and possible widespread roles for ALMS1 in mature cochlear function and homeostasis
  • can contributes to ciliary function in the cochlea
