Cryo-EM structures of γ-TuRC reveal molecular insights into microtubule nucleation
Microtubules within cells often have 13 protofilaments but are nucleated by multi-protein y-TuRCs complexes that display 14 γ-tubulin molecules. High-resolution cryo-EM structures of γ-TuRCs after nucleation show that these γ-TuRCs ‘close’ during nucleation to display only 13 γ-tubulin molecules for protofilament assembly.
期刊介绍：
Nature Structural & Molecular Biology is a comprehensive platform that combines structural and molecular research. Our journal focuses on exploring the functional and mechanistic aspects of biological processes, emphasizing how molecular components collaborate to achieve a particular function. While structural data can shed light on these insights, our publication does not require them as a prerequisite.
