The stoichiometry, location, and structures of these proteins in the context of the native human γ-TuRC were recently identified using high-resolution cryo-EM ( Wieczorek et al., 2020a, b Consolati et al., 2020). In vertebrates, the γ-TuRC contains at least 8 proteins, including γ-tubulin, the γ-tubulin complex proteins (GCPs) 2–6, and the mitotic spindle organizing proteins associated with a ring of γ-tubulin-1 and -2 (MZT1 and MZT2 Murphy et al., 2001 Teixidó-Travesa et al., 2010 Hutchins et al., 2010). The γ-tubulin ring complex (γ-TuRC) is an ∼2.3 MD assembly required for proper microtubule network formation in eukaryotes ( Knop et al., 1997 Raff et al., 1993 Stearns and Kirschner, 1994 Zheng et al., 1995). Our results show that the γ-TuRC can be reconstituted using a limited set of proteins and suggest that the LB facilitates the self-assembly of regulatory interfaces around a microtubule-nucleating “core” in the holocomplex. Electron microscopy reveals that γ-TuRC-GFP resembles the native γ-TuRC architecture, while γ-TuRC ΔLB-GFP adopts a partial cone shape presenting only 8–10 γ-tubulin subunits and lacks a well-ordered lumenal bridge. We show that γ-TuRC ΔLB-GFP nucleates microtubules in a guanine nucleotide–dependent manner and with similar efficiency as the holocomplex. In addition, we generate a subcomplex, γ-TuRC ΔLB-GFP, which lacks MZT1 and actin. Here, we report a biochemical reconstitution of the human γ-TuRC (γ-TuRC-GFP) as a ∼35 S complex that nucleates microtubules in vitro. The challenge of reconstituting the γ-TuRC has limited dissections of its assembly and function. This ∼2.3 MD assembly of >31 proteins includes γ-tubulin and GCP2-6, as well as MZT1 and an actin-like protein in a “lumenal bridge” (LB).
