Microtubules composed of alpha betatubulin dimers are dynamic cytoskeletal polymers that play key roles in essential cellular processes such as cell division, organelle positioning, intracellular transport, and cell migration. gammaTubulin is a highly conserved member of the tubulin family that is required for microtubule nucleation. gammaTubulin, together with its associated proteins, forms the gammatubulin ring complex (gammaTuRC), that templates microtubules. Here we review recent advances in the structure of gammaTuRC, its activation, and centrosomal recruitment. This provides new mechanistic insights into the molecular mechanism of microtubule nucleation. Accumulating data suggest that gammatubulin also has other, less well understood functions. We discuss emerging evidence that gammatubulin can form oligomers and filaments, has specific nuclear functions, and might be involved in centrosomal cross-talk between microtubules and microfilaments.
