An unconventional myosin, myosin 1d regulates Kupffer’s vesicle morphogenesis and laterality

Abstract

INTRODUCTION INTRODUCTION RESULTS MATERIALS AND METHODS AUTHOR CONTRIBUTIONS REFERENCES Establishing left-right (LR) asymmetry is a fundamental process essential for arrangement of visceral organs during development. In vertebrates, motile cilia driven fluid flow in the left-right organizer (LRO) is essential for initiating symmetry breaking event1-3. Without a definite LRO structure in invertebrates, LR asymmetry is initiated at a cellular level by actin-myosin driven chirality4, 5. In Drosophila, myosin1D drives tissue-specific chirality in hind-gut looping6, 7. Here, we show that myosin 1d (myo1d) is essential for establishing LR asymmetry in zebrafish. Using super-r ...
