Contributes to microtubule severing ATPase activity. Involved in microtubule depolymerization. Part of katanin complex. Expressed in amphid neurons; inner labial neurons; outer labial neurons; and phasmid neurons.
Contributes to microtubule severing ATPase activity. Involved in microtubule depolymerization. Part of katanin complex. Human ortholog(s) of this gene implicated in lissencephaly 6. Is an ortholog of human KATNB1 (katanin regulatory subunit B1).
Enables several functions, including ATP binding activity; MATH domain binding activity; and microtubule severing ATPase activity. Involved in several processes, including cytoskeleton organization; female meiotic nuclear division; and negative regulation of meiotic spindle elongation. Located in meiotic spindle pole and nucleus. Part of chromatin and katanin complex. Expressed in ciliated neurons; germ line; and head neurons. Is an ortholog of human KATNA1 (katanin catalytic subunit A1) and KATNAL1 (katanin catalytic subunit A1 like 1).
