Tubulin detyrosination-tyrosination cycle regulates the stability of microtubules. Thus far described on α-tubulins, the tyrosination level is maintained by a single tubulin-tyrosine ligase (TTL). However, the precise dynamics and tubulin isoforms which undergo (de)tyrosination in neurons are unknown. Here, we exploit the substrate promiscuity of the TTL to introduce an O-propargyl-L-tyrosine in neuroblastoma cells and neurons. Mass spectrometry-based chemical proteomics in neuroblas...
