Nearly five decades of research have established myosin as the main motor responsible for cytokinesis in organisms on the branch of the phylogenetic tree that includes amoebas, fungi and animals. This research has grown to be more mechanistic over the past decade, so we now have computer simulations of physically reasonable models that explain how ...

Abstract Myosin A molecules aggregate and form polymers of about 1 μ in length, when the ionic strength of pH of their solution is lowered. In 0.2 M KCl, myosin A is fulully dissociated at pH 7.3 and higher, but fully polymerized at pH 6.5 and lower.

Class XVIII myosins represent a branch of the myosin family tree characterized by the presence of large N- and C-terminal extensions flanking a generic myosin core. These myosins display the highest sequence similarity to conventional class II muscle myosins and are compatible with but not restricted to myosin-2 contractile structures.

The traditional view of myosin, drawn from studies of myosins from striated muscles, is that of an elongated two-headed molecule that assembles into filaments. However, biochemical, molecular genetic and genetic studies have uncovered a host of ubiquitous single-headed nonfilamentous myosins known collectively as myosins I. All of the myosins I possess

Abstract The reaction of succinic anhydride with the free amino groups of myosin introduced a high negative charge density and thus greatly altered the properties of this protein. Succinylated myosin was water-soluble and remained so even after prolonged heating.

The class I myosins are single-headed, actin-binding, mechanochemical “motor” proteins with heavy chains in the molecular mass range of 110-130 kDa; they do not form filaments. Each myosin I heavy chain is associated with one to six light chains that bind to specific motifs known as IQ domains.

Directed movements on actin filaments within the cell are powered by molecular motors of the myosin superfamily. On actin filaments, myosin motors convert the energy from ATP into force and movement. Myosin motors power such diverse cellular functions as cytokinesis, membrane trafficking, organelle movements, and cellular migration.

Myosins constitute a superfamily of actin-based molecular motor proteins that mediates a variety of cellular activities including muscle contraction, cell migration, intracellular transport, the formation of membrane projections, cell adhesion, and cell signaling. The 12 myosin classes that are expressed in humans share sequence similarities especially

Abstract Myosin and its helical subfragments form bipolar “segment” aggregates which may be related to the bare zone of the thick filament. Two distinct modes of aggregation have now been observed: one with an overlap of 1300 A and another with an overlap of about 900 A. Both are consistent with a value of 1450 A for the length of the rod.

Hearing loss is both genetically and clinically heterogeneous, and pathogenic variants of over a hundred different genes are associated with this common neurosensory disorder. A relatively large number of these "deafness genes" encode myosin super family members.
