  • The formation of branched microtubule networks in mitotic spindles depends on the augmin complex. Zupa, Würtz et al. elucidate the molecular architecture and conformational plasticity of the augmin complex using integrative structural biology, providing structural insights into microtubule branching.

  • The nucleation of microtubules from αβ-tubulin subunits is mediated by γtubulin complexes, which vary in composition across organisms. Here, authors present the cryo-EM structure of the heterotetrameric γ-tubulin small complex (γ-TuSC) from C. albicans at near-atomic resolution.

  • The human microtubule nucleator γ-TuRC is composed of more than thirty subunits, including actin. Here the authors reveal the structural mechanism of modular γ-TuRC assembly and show a functional role of actin in microtubule nucleation.

  • The cryo-EM structure of the γ-tubulin ring complex (γ-TuRC) from Xenopus laevis provides insights into the molecular organization of the complex, and shows that actin is a structural component that is functionally relevant to microtubule nucleation.
