Regulation of microtubule stability by centrosomal proteins.

The centrosome executes diverse functions including the nucleation and organization of microtubules. A subset of centrosomal proteins is found to be involved in regulating the nucleation, stability, and dynamics of microtubules. Literature is flooded with reports of centrosomal proteins regulating microtubule nucleation. However, the centrosomal proteins that regulate microtubule stability are underexplored. Here, we review the centrosomal proteins, which either enhance or reduce the stability of microtubules and thereby regulate microtubule dynamics. We also discuss unexplored aspects of the centrosomal proteins that influence microtubule stability. © 2018 IUBMB Life, 70(7):602-611, 2018.
