What is the Role of γ-Tubulin in Microtubule Nucleation?
γ-Tubulin is a critical component of the γTuRC, which serves as a nucleation template. The γTuRC caps the minus end of the microtubule, allowing rapid elongation at the plus end. By providing a stable platform for the initial assembly of tubulin dimers, γ-tubulin ensures efficient and accurate microtubule formation.
