CC -!- FUNCTION: Participates in a complex which severs microtubules in an
CC ATP-dependent manner. May act to target the enzymatic subunit of this
CC complex to sites of action such as the centrosome. Microtubule severing
CC may promote rapid reorganization of cellular microtubule arrays and the
CC release of microtubules from the centrosome following nucleation.
CC {ECO:0000255|HAMAP-Rule:MF_03022}.
CC -!- SUBUNIT: Interacts with katna1. This interaction enhances the
CC microtubule binding and severing activity of katna1 and also targets
CC this activity to the centrosome. {ECO:0000255|HAMAP-Rule:MF_03022}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03022}.
CC Cytoplasm, cytoskeleton, microtubule organizing center, centrosome
CC {ECO:0000255|HAMAP-Rule:MF_03022}. Cytoplasm, cytoskeleton, spindle
CC pole {ECO:0000255|HAMAP-Rule:MF_03022}. Cytoplasm, cytoskeleton
CC {ECO:0000255|HAMAP-Rule:MF_03022}. Cytoplasm, cytoskeleton, spindle
CC {ECO:0000250|UniProtKB:Q9BVA0}. Note=Predominantly cytoplasmic.
CC Localized to the interphase centrosome and mitotic spindle poles.
CC {ECO:0000255|HAMAP-Rule:MF_03022}.
CC -!- DISRUPTION PHENOTYPE: Results in a significant reduction in midbrain
CC size. A wide spectrum of defects in gastrulation and formation of
CC anterior structures are noticed, ranging from milder microcephaly to
CC more severe anencephaly and early embryonic death.
CC {ECO:0000269|PubMed:25521378, ECO:0000269|PubMed:25521379}.
CC -!- SIMILARITY: Belongs to the WD repeat KATNB1 family. {ECO:0000255|HAMAP-
CC Rule:MF_03022}.
