May influence the stability of microtubules (MT), possibly through interaction with the MT-severing katanin complex. Interacts with microtubules. Interacts with 4 subunits of the katanin complex: KATNA1, KATNAL1, KATNB1 and KATNBL1. When overexpressed, localizes to the cytoplasm where it associates with acetylated alpha-tubulin. The disease is caused by variants affecting the gene represented in this entry. Extended N-terminus.
