GIPC3, multifunctional myosin adaptor in mammalian auditory hair cells
GIPC3, a member of Gα-Interacting Protein, C-terminus (GIPC) family, is known to be essential for hearing. Eleven mutations in GIPC3, spread throughout its three structural domains, cause inherited autosomal recessive hearing loss. However, the molecular basis for GIPC3 function in the auditory system and the mechanisms by which these human mutations result in hearing loss are unknown. We have recently determined the structure of GIPC3 bound to a prototypical receptor and determined the molecular mechanism of GIPC3 activation and its subsequent binding to MYO6, the unconventional myosin that is expressed in the auditory hair cells and is essential for hearing. These biochemical and…
