Molecular characterization and subcellular localization of arabidopsis class viii myosin, ATM1

Abstract

Background: Molecular properties of class VIII myosin are not characterized. Results: Arabidopsis class VIII myosin, ATM1, has low enzymatic activity and high affinity for actin and is primarily localized at the cell cortex. Conclusion: Our data suggest that ATM1 functions as a tension sensor/generator. Significance: This is the first report of enzymatic and motile properties of class VIII myosin. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.
