Abstract

Microtubules are a major component of the cytoskeleton and can accumulate a plethora of modifications. The microtubule detyrosination cycle is one of these modifications; it involves the enzymatic removal of the C-terminal tyrosine of α-tubulin on assembled microtubules and the re-ligation of tyrosine on detyrosinated tubulin dimers. This modification cycle has been implicated in cardiac disease, neuronal development, and mitotic defects. The vasohibin and microtubule-associated tyrosine carboxypeptidase enzyme families are responsible for microtubule detyrosination. Their long-sought discovery allows to review and summarise differences and similarities between the two enzymes families and discuss how they interplay with other modifications and functions of the tubulin code.
