Function

[MYO2_YEAST] Myosin heavy chain that is required for the cell cycle-regulated transport of various organelles and proteins for their segregation. Functions by binding with its tail domain to receptor proteins on organelles and exerting force with its N-terminal motor domain against actin filaments, thereby transporting its cargo along polarized actin cables. Essential for the delivery of secretory vesicles to sites of active growth during bud emergence and cytokinesis. Required for segregation and inheritance of peroxisomes, late Golgi compartments, mitochondria and the vacuole to the daughter cell during cell division. Also required for correct alignment of the spindle during mitosis.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8]

Publication Abstract from PubMed

Myosin V molecular motors move cargoes on actin filaments. A myosin V may move multiple cargoes to distinct places at different times. The cargoes attach to the globular tail of myosin V via cargo-specific receptors. Here we report the crystal structure at 2.2 A of the myosin V globular tail. The overall tertiary structure has not been previously observed. There are several patches of highly conserved regions distributed on the surface of the tail. These are candidate attachment sites for cargo-specific receptors. Indeed, we identified a region of five conserved surface residues that are solely required for vacuole inheritance. Likewise, we identified a region of five conserved surface residues that are required for secretory vesicle movement, but not vacuole movement. These two regions are at opposite ends of the oblong-shaped cargo-binding domain, and moreover are offset by 180 degrees. The fact that the cargo-binding areas are distant from each other and simultaneously exposed on the surface of the globular tail suggests that major targets for the regulation of cargo attachment are organelle-specific myosin V receptors.
