| General Comments |
|
Katanin is a hydrolase enzyme composed of an ATP-dependent p60 catalytic subunit (KATNA1) and a p80 regulatory subunit (KATNB1) which targets the enzyme to the centrosome [1]. Katanin is required during meiosis and mitosis, being involved in dissasembling microtubules from their interphase structures and segregating chromatids towards the spindle pole during cell division [3]. Novel anti-cancer agents which induce microtubule fragmentation via interaction with katanin are being investigated [2]- see compound 5a [PMID: 27536893] for example. |
