Dissecting the role of the tubulin code in mitosis.

ABSTRACT: Mitosis is an essential process that takes place in all eukaryotes and involves the equal division of genetic material from a parental cell into two identical daughter cells. During mitosis, chromosome movement and segregation are orchestrated by a specialized structure known as the mitotic spindle, composed of a bipolar array of microtubules. The fundamental structure of microtubules comprises of α/β-tubulin heterodimers that associate head-to-tail and laterally to form hollow filaments. In vivo, microtubules are modified by abundant and evolutionarily conserved tubulin posttranslational modifications (PTMs), giving these filaments the potential for a wide chemical diversity. In recent years, the concept of a "tubulin code" has emerged as an extralayer of regulation governing microtubule
