The Myosin Filament: XI Filament Assembly

Preparative Biochemistry, 1986
The critical parameters required for the assembly of myosin filaments with a length distribution comparable to that for native myosin filaments were examined. It was found that: Two steps are required in the dilution of a myosin solution from 0.6M KCl to 0.15M KCl.

TWISTED DWARF1 mediates myosin XI-associated vesicle trafficking required for auxin transport

2022
ABSTRACTDefects in plant development caused by loss-of the FKBP42, TWISTED DWARF1 (TWD1), have so far been accounted to a dual function of TWD1 acting as an ABCB chaperone that positively regulates ABCB biogenesis and transport activity. On the other hand, TWD1 was characterized as a modulator of actin cytoskeleton bundling and dynamics by interaction ...

Plant Myosins VIII, XI, And XIII

2007
There are three classes of myosins in plants: myosins VIII, XI, and XIII. Myosins VIII and XI are widely distributed and found not only in higher plants, but also in Chlamydomonas, while myosin XIII is found only in Acetabularia. Biochemical studies have been done mainly on myosin XI, which is the most abundantly expressed myosin in plants.

Dictyostelium discoideum myoJ: a member of a broadly defined myosin V class or a class XI unconventional myosin?

Journal of Muscle Research and Cell Motility, 1996
The simple eukaryote Dictyostelium discoideum contains at least 12 unconventional myosin genes. Here we report the characterization of one of these, myoJ, a gene initially identified through a physical mapping screen. The myoJ gene encodes a high molecular weight myosin, and analysis of the available deduced amino acid sequence reveals that it ...

The role of class XI myosin in fertilization of Arabidopsis thaliana

2022
Fertilization is the process of fusion of haploid male and female gametes to develop a new individual. In most animals, microtubules drive the migration of the female pronucleus toward the male pronucleus for fertilization. By contrast, the fertilization process in flowering plants is dependent on actin filament (F-actin) dynamics; F-actin, not ...

Myosin XI, a model of its conserved role in plant cell tip growth

Biochemical Society Transactions
In eukaryotic cells, organelle and vesicle transport, positioning, and interactions play crucial roles in cytoplasmic organization and function. These processes are governed by intracellular trafficking mechanisms. At the core of that trafficking, the cytoskeleton and directional transport by motor proteins stand out as its key regulators.
