Two proteins implicated in inherited deafness, myosin IIIa, a plus-end-directed motor, and espin, an actin-bundling protein containing the actin-monomer-binding motif WH2, have been shown to influence the length of mechanosensory stereocilia. Here we report that espin 1, an ankyrin repeat-containing...
