Cross-linking/mass spectrometry analysis of AUGMIN complex


ABSTRACT: We applied cross-linking/mass spectrometry to characterize in vivo Augmin from Drosophila in absence of any other structural information. The identified cross-links revealed topology of the Augmin complex and allowed us to predict potential interfaces between Augmin and γ-TuRC.

The hetero-octameric protein complex, Augmin, recruits γ-Tubulin ring complex (γ-TuRC) to pre-existing microtubules (MTs) to generate branched MTs during mitosis, facilitating robust spindle assembly. However, despite a recent partial reconstitution of the human Augmin complex <i>in vitro</i>, the molecular basis of this recruitment remains unclear. Here, we used immuno-affinity purification of <i>in vivo</i> Augmin from <i>Drosophila</i> and cross-linking/mass spectrometry to identify distance  ...[more]
