Unraveling the fastest myosin: Discovery history and structure-function relationships of algae Chara myosin XI [PDF]
Biophysics and PhysicobiologyPlant myosins have higher velocities than animal myosins. Among them, myosins in freshwater algae of the genus Chara have extremely high velocities. We have biochemically studied myosins that perform high-speed movements in the alga Chara.

Single-molecule fluorescence microscopy reveals regulatory mechanisms of MYO7A-driven cargo transport in stereocilia of live inner ear hair cells [PDF]
Nature CommunicationsStereocilia are F-actin-based cylindrical protrusions on the apical surface of inner ear hair cells that function as biological mechanosensors of sound and acceleration.

Long-tailed class I myosins rely on tail-mediated phosphoinositide recognition for specific membrane recruitment [PDF]
Cell Communication and SignalingBackground Class I myosins are essential mediators of membrane–cytoskeleton interactions that support key cellular processes such as endocytosis, secretion, intracellular trafficking, and mitosis.

The class II myosin MYH4 safeguards genome integrity and suppresses tumor progression [PDF]
The Journal of Clinical InvestigationLoss-of-function mutations in genome maintenance genes fuel tumorigenesis through increased genomic instability. A subset of these tumor suppressors are challenging to identify due to context dependency, including functional interactions with other genes

Gliding motility of the diatom Craspedostauros australis coincides with the intracellular movement of raphid-specific myosins [PDF]
Communications BiologyRaphid diatoms are one of the few eukaryotes capable of gliding motility, which is remarkably fast and allows for quasi-instantaneous directional reversals.

Class I Myosins, molecular motors involved in cell migration and cancer
Cell Adhesion & Migration, 2022 Class I Myosins are a subfamily of motor proteins with ATPase activity and a characteristic structure conserved in all myosins: A N-Terminal Motor Domain, a central Neck and a C terminal Tail domain. Humans have eight genes for these myosins.

Functional Role of Class III Myosins in Hair Cells
Frontiers in Cell and Developmental Biology, 2021 Cytoskeletal motors produce force and motion using the energy from ATP hydrolysis and function in a variety of mechanical roles in cells including muscle contraction, cargo transport, and cell division.

Non-muscle myosins control the integrity of cortical radial glial endfeet
PLoS Biology, 2023 Radial glial cells, the stem cells of the cerebral cortex, extend a long basal fiber that ends in basal endfeet. A new study in PLOS Biology found that non-muscle myosins control basal endfoot integrity to regulate interneuron organization.

The loop2 insertion of type IX myosin acts as an electrostatic actin tether that permits processive movement. [PDF]
PLoS ONE, 2014 Although class IX myosins are single-headed, they demonstrate characteristics of processive movement along actin filaments. Double-headed myosins that move processively along actin filaments achieve this by successive binding of the two heads in a hand ...
