CC -!- FUNCTION: Plus-end directed kinesin-like motor enzyme involved in
CC mitotic spindle assembly. Required for centrosome separation and
CC maintenance of spindle bipolarity during mitosis.
CC {ECO:0000269|PubMed:8548825}.
CC -!- SUBUNIT: Homodimer. Dimerization is required for targeting to
CC microtubule minus ends. Found in a complex with tpx2 and microtubules.
CC Its association with microtubules and targeting to microtubule minus
CC ends requires tpx2. {ECO:0000269|PubMed:10871281,
CC ECO:0000269|PubMed:9813089}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, cytoskeleton, microtubule
CC organizing center, centrosome. Cytoplasm, cytoskeleton, spindle.
CC Cytoplasm, cytoskeleton, spindle pole. Note=Localizes during metaphase
CC on spindle microtubules, with a strong enrichment at spindle poles.
CC Localizes to the minus ends of spindle pole and aster microtubules in a
CC dynein- and dynactin-dependent manner. Detected diffusively in the
CC cytoplasm. Localized (PubMed:8548825) at the centrosome during the
CC interphase and throughout mitosis. {ECO:0000269|PubMed:8548825}.
CC -!- TISSUE SPECIFICITY: Strongly expressed in testis and weakly in lung (at
CC protein level). {ECO:0000269|PubMed:8548825}.
CC -!- DEVELOPMENTAL STAGE: Expressed maternally in oocytes and eggs (at
CC protein level). {ECO:0000269|PubMed:8548825}.
CC -!- SIMILARITY: Belongs to the TRAFAC class myosin-kinesin ATPase
CC superfamily. Kinesin family. KLP2 subfamily. {ECO:0000255|PROSITE-
CC ProRule:PRU00283}.
