Abstract:
Myosin-1c is an unconventional myosin involved in hair-cell mechanotransduction, a process that underlies our senses of hearing and balance. To study the interaction of myosin-1c with other components of the hair-cell transduction complex, we have developed an in situ binding assay that permits visualization of myosin-1c binding to hair-cell proteins. In this chapter we describe in detail the methods needed for the expression and purification of recombinant myosin-1c fragments and their use in the in situ binding assay.
