Employing structural biology approaches including protein expression and purification, data collection and analysis, this work ultimately determines the protein structures of key cell motility molecular motors. The findings of this study mainly reveal the motility and walking mechanism of cilia-associated kinesins, clarify the regulatory mechanisms underlying ciliary assembly and central microtubule formation, identify key regulatory factors of molecular motors involved in ciliary cargo transport, and provide a theoretical foundation for further understanding of cilia-related cell motility driven by molecular motors.
