Tip links between adjacent stereocilia are believed to gate mechano-electrical transducer (MET) channels and mediate the electrical responses of sensory hair cells. We found that mouse auditory hair cells that lack tip links due to genetic mutations or exposure to

Ubiquitination governs oscillation of cyclin-dependent kinase (CDK) activity through a periodic degradation of cyclins for orderly cell cycle progression; however, the mechanism that maintains the constant CDK protein levels throughout the cell cycle remains unclear. Here we show that CDK6
