Impact of the 'tubulin economy'on the formation and function of the microtubule cytoskeleton

R Ohi, C Strothman, M Zanic - Current opinion in cell biology, 2021 - Elsevier
The microtubule cytoskeleton is assembled from a finite pool of α, β-tubulin, the size of which
is controlled by an autoregulation mechanism. Cells also tightly regulate the architecture …
