Structural basis of cargo recognition by the myosin-X MyTH4–FERM domain
Myosin-X is an important unconventional myosin that is critical for cargo transportation to filopodia tips and is also utilized in spindle assembly by interacting with microtubules. We present a series of structural and biochemical studies of the myosin-X tail domain cassette, consisting of myosin tail homology 4 (MyTH4) and FERM domains in complex with its specific cargo, a netrin receptor DCC...
متن کاملCargo recognition mechanism of myosin X revealed by the structure of its tail MyTH4-FERM tandem in complex with the DCC P3 domain.
Myosin X (MyoX), encoded by Myo10, is a representative member of the MyTH4-FERM domain-containing myosins, and this family of unconventional myosins shares common functions in promoting formation of filopodia/stereocilia structures in many cell types with unknown mechanisms. Here, we present the structure of the MyoX MyTH4-FERM tandem in complex with the cytoplasmic tail P3 domain of the netrin...
متن کاملStructure of Myo7b/USH1C complex suggests a general PDZ domain binding mode by MyTH4-FERM myosins.
Unconventional myosin 7a (Myo7a), myosin 7b (Myo7b), and myosin 15a (Myo15a) all contain MyTH4-FERM domains (myosin tail homology 4-band 4.1, ezrin, radixin, moesin; MF) in their cargo binding tails and are essential for the growth and function of microvilli and stereocilia. Numerous mutations have been identified in the MyTH4-FERM tandems of these myosins in patients suffering visual and heari...
متن کاملCharacterization of a myosin VII MyTH/FERM domain.
A group of closely related myosins is characterized by the presence of at least one MyTH/FERM (myosin tail homology; band 4.1, ezrin, radixin, moesin) domain in their C-terminal tails. This domain interacts with a variety of binding partners, and mutations in either the MyTH4 or the FERM domain of myosin VII and myosin XV result in deafness, highlighting the functional importance of each domain...
متن کاملMyTH4-FERM myosins have an ancient and conserved role in filopod formation.
The formation of filopodia in Metazoa and Amoebozoa requires the activity of myosin 10 (Myo10) in mammalian cells and of Dictyostelium unconventional myosin 7 (DdMyo7) in the social amoeba Dictyostelium However, the exact roles of these MyTH4-FERM myosins (myosin tail homology 4-band 4.1, ezrin, radixin, moesin; MF) in the initiation and elongation of filopodia are not well defined and may refl...
