Abstract (EN): 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 alpha/ss-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 function. A range of tubulin isoforms, each with a diverse set of PTMs, provides a readable code for microtubule motors and other microtubule-associated proteins. This chapter focuses on the complexity of tubulin PTMs with an emphasis on detyrosination and summarizes the methods currently used in our laboratory to experimentally manipulate these modifications and study their impact in mitosis.
