The paper identifies a myosin filament cage in polarized epithelial cells that drives planar division and asymmetric cleavage, and shows its disruption leads to orthogonal division and multiple lumens.

This study identifies Myo10 as critical for dendritic cell migration through complex tissues, showing it coordinates leading-edge dynamics via lamellipodin and VASP.

This paper develops a FRET-based tension sensor (mDia1TS) to measure mechanical tension in formin-elongated actin filaments in live cells and quantifies changes in tension under different conditions.

This study shows that NM IIA limits A/E bacterial colonization by inhibiting actin pedestal formation, while NM IIC does not play a similar role.

This study shows that myosin 18Aα recruits β-Pix to dendritic spines in Purkinje neurons, enhancing spine maturation through actin and myosin filament assembly.

The paper shows that endoplasmic reticulum (ER) visits active dendritic spines to prevent excessive synaptic potentiation.

This study identifies myosin V as essential for synaptopodin clustering at post-synaptic sites, showing that the spine apparatus is assembled locally rather than transported.
