H. Aldaz et al., "Insights into microtubule nucleation from the crystal structure of human β-tubulin,"
The authors have determined the crystal structure of γ-tubulin bound to GTP-γ S (a non-hydrolyzable GTP analog) at 2.7 Å resolution. γ-tubulin forms part of the γ-tubulin ring complex (γ-TuRC) required for microtubule assembly. Comparison of the structure determined with several others from the αβ-heterodimer ... strongly suggests a mechanism of microtubule nucleation in which lateral association of γ-tubulin molecules plays a critical role.
