TUBA1A and tubulinopathy: Here we harness a previously-identified internal loop within TUBA1A that tolerates addition of small epitope tags without impacting TUBA1A incorporation or dynamics (Schatz et al., 1987; Heilemann et al., 2008; Hotta et al., 2016) to generate an important tool for the study of tubulinopathies and neuronal α-tubulin.
