Secondry Information

Protein Function motor protein involved in epithelial spindle dynamics; Depletion of Myo10 results in spindle lengthening, pole fragmentation, and metaphase delay; the requirement for Myo10 in spindle pole integrity is F-actin independent; participates in essential intracellular processes such as filopodia formation/extension, phagocytosis, cell migration, and mitotic spindle maintenance
Biochemical Properties binds to Wee1, a conserved regulator of cyclin-dependent kinase 1; majority of molecules are dimeric with a head-to-head contour distance of ∼50 nm; motility assays show that myosin- 10 moves actin filaments smoothly with a velocity of ∼310 nm/s; Single molecule optical tweezers experiments show that under intermediate load (∼0.5 pN), myosin- 10 interacts intermittently with actin and produces a power stroke of ∼17 nm, composed of an initial 15-nm and subsequent 2-nm movement; ATPase activity was found to be regulated both by Ca2+ and phospholipids
Significance in milk Cytoskeletal proteins; found increased during infection
Additional Comments Myo10 association is critical for the bacterial infection to spread; the role of Myo10 and filopodia in bacterial infection as well. Shigella flexneri is an intracellular pathogen that primarily infects mammalian epithelial cells. In order to enter eukaryotic cells, Shigella can be captured by filopodia, which then retract bringing the bacteria to the cell body
