Abstract:
Myosin-X (MYO10) is an actin-based motor protein involved in cytoskeletal dynamics, membrane interactions, and integrin-mediated adhesion. To investigate MYO10's cellular roles, we generated MYO10 knockdown (MYO10 KD ) HeLa and COS7 cell lines using lentiviral shRNA. Compared to wild-type cells, both MYO10 KD lines showed reduced proliferation and impaired cell migration in wound assays. Additionally, there were fewer edge filopodia in HeLa cells. Furthermore, MYO10 KD cells demonstrated increased spreading on laminin-coated substrates, suggesting altered integrin activation and cytoskeletal linkage. Our results reinforce MYO10's importance in cell proliferation, adhesion, and migration. These MYO10 KD lines provide an accessible cell culture model for future study of MYO10.

Role of Myosin in Cell Migration
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....
