[https://www.uniprot.org/uniprot/MYO5A_CHICK MYO5A_CHICK] Processive actin-based motor that can move in large steps approximating the 36-nm pseudo-repeat of the actin filament. Involved in melanosome transport. Also mediates the transport of vesicles to the plasma membrane. May also be required for some polarization process involved in dendrite formation (By similarity).

== Publication Abstract from PubMed ==
 +
The molecular motor, myosin, undergoes conformational changes in order to convert chemical energy into force production. Based on kinetic and structural considerations, we assert that three crystal forms of the myosin V motor delineate the conformational changes that myosin motors undergo upon detachment from actin. First, a motor domain structure demonstrates that nucleotide-free myosin V adopts a specific state (rigor-like) that is not influenced by crystal packing. A second structure reveals an actomyosin state that favors rapid release of ADP, and differs from the rigor-like state by a P-loop rearrangement. Comparison of these structures with a third structure, a 2.0 angstroms resolution structure of the motor bound to an ATP analog, illuminates the structural features that provide communication between the actin interface and nucleotide-binding site. Paramount among these is a region we name the transducer, which is composed of the seven-stranded beta-sheet and associated loops and linkers. Reminiscent of the beta-sheet distortion of the F1-ATPase, sequential distortion of this transducer region likely controls sequential release of products from the nucleotide pocket during force generation.
