Function
KTNA1_CAEEL Catalytic subunit of a complex which severs microtubules in an ATP-dependent manner. Microtubule severing may promote rapid reorganization of cellular microtubule arrays. Required specifically for meiotic spindle formation in the female germline; the presence of this protein is inimical to the formation of mitotic spindles (PubMed:8027178, PubMed:10809666, PubMed:12885567). In body wall muscles, regulates organization of myosin thick filaments (PubMed:22621901).[HAMAP-Rule:MF_03023][1] [2] [3] [4]
