Abstract

Background: Class III myosins contain both a motor and kinase domain. Results: Phosphorylation of the kinase activation loop enhances MYO3A kinase activity, augmenting autophosphorylation induced attenuation of motor and cellular activity. Conclusion: MYO3A kinase activity mediates localization and function within actin protrusions. Significance: Characterizing MYO3A kinase regulation enhances our understanding of the role of MYO3A in the maintenance of actin protrusions found in sensory epithelia.
