The Myo1c motor functions as a cargo transporter supporting various cellular
events, including vesicular trafficking, cell migration, and stereociliary
movements of hair cells. Although its partial crystal structures were recently
described, the structural details of its interaction with cargo proteins remain
unknown. This study presents the first structural demonstration of a cargo
protein, Neph1, attached to Myo1c, providing novel insights into the role of
Myo1c in intracellular movements of this critical slit diaphragm protein. Using
small angle X-ray scattering studies, models of predominant solution conformation
of unliganded full-length Myo1c and Myo1c bound to Neph1 were constructed. The
resulting structures show an extended S-shaped Myo1c with Neph1 attached to its
C-terminal tail. Importantly, binding of Neph1 did not induce a significant shape
change in Myo1c, indicating this as a spontaneous process or event. Analysis of
interaction surfaces led to the identification of a critical residue in Neph1
involved in binding to Myo1c. Indeed, a point mutant from this site abolished
interaction between Neph1 and Myo1c when tested in the in vitro and in live-cell
binding assays. Live-cell imaging, including fluorescence recovery after
photobleaching, provided further support for the role of Myo1c in intracellular
vesicular movement of Neph1 and its turnover at the membrane.
