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...

Viruses influence ecosystems by modulating microbial population size, diversity, metabolic outputs, and gene flow. Here, we use quantitative double-stranded DNA (dsDNA) viral-fraction metagenomes (viromes) and whole viral community morphological data sets from 43 Tara Oceans expedition samples to assess viral...

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...
